Selective syntheses of aliphatic carboxylic acids, esters, and amides using sodium tetracarbonylferrate(-II) was written by Collman, James P.;Winter, Stanley R.;Komoto, Robert G.. And the article was included in Journal of the American Chemical Society in 1973.Application In Synthesis of Ethyl methyl adipate The following contents are mentioned in the article:

New routes have been developed for the conversion of alkyl halides and tosylates into carboxylic acids, esters, and amides using sodium tetracarbonylferrate(-II). Carboxylic acids are obtained from alkyl or acyl tetracarbonylferrate(0) intermediates using O2, NaClO, or I2/H2O. Esters and amides are obtained from the same intermediates using I2/ROH and I2/RR’NH resp. Advantages of these syntheses lie in their selectivity between halides and in their toleration of a wide range of functional groups including carbonyl groups. In addition, it is likely that the stereospecificity observed in one of our earlier ketone synthesis will be also found in these reactions. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Application In Synthesis of Ethyl methyl adipate).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Application In Synthesis of Ethyl methyl adipate

A highly stereoselective synthesis of (E)-enol lactones by the Wittig reaction of cyclic anhydrides with (α-alkoxycarbonylethylidene)triphenylphosphorane was written by Tsuboi, Sadao;Fukumoto, Hirohumi;Wada, Hiroshi;Takeda, Akira;Fukuyama, Keiichi. And the article was included in Bulletin of the Chemical Society of Japan in 1987.Synthetic Route of C9H16O4 The following contents are mentioned in the article:

The Wittig reaction of Ph₃P:CMeCO₂R (I; R = Et, Me₃C) with glutaric anhydrides II (R¹, R³, R⁴ = H, Me; R² = H, Me, Ph) gave 13-86% exo-(alkoxycarbonyl)heptenolides III and 6-35% endo-(alkoxycarbonyl)heptenolides IV (R-R⁴ = same as above). (E)-III were obtained with high stereoselectivity. X-ray crystal anal. of III (R = Me₃C, R¹ = Me, R²-R⁴ = H) confirmed the stereochem. assigned. The Wittig reactions of I with adipic and azelaic anhydrides are also reported. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Synthetic Route of C9H16O4).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Synthetic Route of C9H16O4

Contributions from the Laboratories of the Heriot Watt College, Edinburgh. The synthetical formation of closed carbon chains. Part I (continued). Action of propylene bromide on the sodium compounds of ethyl acetoacetate and ethyl benzoylacetate was written by Perkin, W. H.;Stenhouse, James. And the article was included in Journal of the Chemical Society, Transactions in 1892.Category: esters-buliding-blocks The following contents are mentioned in the article:

The action of propylene bromide on the sodium compounds of ethyl acetoacetate and ethyl benzoylacetate was studied. Propylene bromide did not react with these compounds, the yield of ethereal salt obtained was very small . To obtain sufficient material for the experiments, the fraction of the ethereal salt boiling at 196°-225°, which consisted for the most part of ethyl acetylmethyltrimethylenecarboxylate was hydrolyzed. Acetyltrimethylenecarboxylate acid when treated with hydroxylamine in alkaline solution yielded an oxime proving that it contained a carbonyl group, this acid and acetylmethyltrimethylenecarboxylic acid were similarly constituted. Acetylmethyltrimethylenecarboxylic acid oxime melts at 153°-155° with decomposition. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Category: esters-buliding-blocks).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

The effect of biodiesel fuels on transient emissions from modern diesel engines, Part II. Unregulated emissions and chemical characterization was written by Sharp, Christopher A.;Howell, Steve A.;Jobe, Joe. And the article was included in Society of Automotive Engineers in 2000.Computed Properties of C9H16O4 The following contents are mentioned in the article:

As part of Tier 1 compliance requirements for EPA’s Fuel Registration Program, a detailed chem. characterization of the transient exhaust emissions of biodiesel from 3 modern diesel engines was performed, both with and without oxidation catalyst. This characterization included several forms of hydrocarbon speciation, and measurement of aldehydes, ketones, and alcs. In addition, both particle-phase and semivolatile-phase PAH and nitro-PAH compounds were measured. Unregulated emissions were characterized with neat biodiesel and with a blend of biodiesel and conventional diesel fuel. Chem. characterization revealed lower levels of some toxic and reactive hydrocarbon species when biodiesel fuels were used. In addition, emissions of PAH and nitro-PAH compounds were substantially lower with biodiesel, as compared to conventional diesel fuel. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Computed Properties of C9H16O4).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Computed Properties of C9H16O4

Photochemical reactions of 2-(alkoxycarbonyl)-, 2-cyano-, and 2-(phenylthio)cycloalkanones in alcoholic solution. Formation of ω-substituted esters was written by Tokuda, Masao;Watanabe, Yasuyuki;Itoh, Mitsuomi. And the article was included in Bulletin of the Chemical Society of Japan in 1978.Related Products of 18891-13-9 The following contents are mentioned in the article:

Photochem. reaction of Et 2-oxo-1-cyclohexanecarboxylate (I) in MeOH gave Et Me heptanedioate, trans– and cis-Et 7-oxo-2-heptenoate, and Et 7-oxo-3-heptenoate in 25, 7, 8, and 21% yields, resp. Photochem. reactions of I in EtOH, iso-PrOH, tert-BuOH gave the corresponding ω-alkoxycarbonyl esters. Other 2-(alkoxycarbonyl)cyclopentanones and -cycloheptanones underwent similar reactions to give the corresponding ω-alkoxycarbonyl esters. Photochem. reactions of 2-cyanocyclohexanones in MeOH similarly gave ω-cyano esters and ω-formyl α,β-unsaturated nitriles. However, photochem. reactions of 2-(phenylthio)- and 2-(methylthio)cyclohexanones in MeOH did not give the corresponding ω-phenylthio or ω-methylthio carboxylic acid esters, products resulting from cleavage of a carbon-sulfur bond being obtained. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Related Products of 18891-13-9).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Related Products of 18891-13-9

Generation of β-carbonyl radicals from cyclopropanol derivatives by oxidation with manganese(III) 2-pyridinecarboxylate and their reactions with electron-rich and -deficient olefins was written by Iwasawa, Nobuharu;Hayakawa, Satoshi;Funahashi, Masahiro;Isobe, Koichi;Narasaka, Koichi. And the article was included in Bulletin of the Chemical Society of Japan in 1993.COA of Formula: C9H16O4 The following contents are mentioned in the article:

Various β-carbonyl radicals are generated oxidatively from cyclopropanol derivatives by the use of manganese(III) 2-pyridinecarboxylate [Mn(pic)₃]. These β-carbonyl radicals react with electron-rich olefins such as conjugated silyl enol ethers, a ketene thioacetal, a ketene dithioacetal, and a vinyl ether intermolecularly to give crossed-addition products in good yield. Thus, 1-phenylcyclopropanol and CH₂:CPhOSiMe₂CMe₃ afforded 89% PhCO(CH₂)₃COPh. Furthermore, the combined use of Mn(pic)₃ and tributylhydridotin makes it possible to carry out the 1:1 addition reaction of these β-carbonyl radicals with electron-deficient olefins such as acrylonitrile, acrylaldehyde, Me acrylate, Me vinyl ketone, and N,N-dimethylacrylamide; the corresponding products are obtained in moderate to good yield.

A Ru-Sn-Co/AlO(OH) as a highly efficient catalyst for hydrogenation of dimethyl adipate to 1,6-hexanediol in aqueous phase was written by Jiang, Hong-Bin;Jiang, Hai-Jun;Su, Ke;Zhu, De-Ming;Zheng, Xue-Li;Fu, Hai-Yan;Chen, Hua;Li, Rui-Xiang. And the article was included in Applied Catalysis, A: General in 2012.Computed Properties of C9H16O4 The following contents are mentioned in the article:

A Ru-Sn-Co/AlO(OH) catalyst was prepared by co-impregnation, calcination, and hydrothermal reduction The catalyst was well characterized by BET, x-ray diffraction, SEM-EDX, XPS, H₂-TPR, and Mossbauer spectroscopy, and then it was applied in the hydrogenation of di-Me adipate to 1,6-hexanediol in aqueous phase. It was found that the addition of cobalt could stabilize Sn(IV) and the cooperation between tin and cobalt could promote the reduction of ruthenium oxide. The γ-Al₂O₃ in the catalyst Ru-Sn-Co/γ-Al₂O₃ was transformed to AlO(OH) by the hydrothermal reduction It was suggested that the stabilized Sn(IV) and the interaction between the hydroxyl group on the surface of AlO(OH) and the solvent water played a key role to improve the conversion of di-Me adipate and the selectivity to 1,6-hexanediol. The conversion of di-Me adipate and the selectivity to 1,6-hexanediol were up to 98% and 95%, resp., under 5 MPa of H₂ and 493 K for 10 h.

Analysis of allelochemicals and allelopathic effect of rhizosphere soils of newly planted and ratoon sugarcane (Saccharum officinarum L.) was written by Zhang, Ai-Jia;Yuan, Zhao-Nian;Chen, Dong-Mei;Wang, Hai-Bin;Wu, Wen-Xiang;Lin, Sheng;Chen, Ting;Chen, Lan-Lan;Fang, Chang-Xun;Lin, Wen-Xiong. And the article was included in Zhongguo Shengtai Nongye Xuebao in 2010.Quality Control of Ethyl methyl adipate The following contents are mentioned in the article:

An experiment was conducted on the allelopathic effects of rhizospheric soil extracts (by water and polarity solvents) from newly planted and ratoon sugarcane (‘FN28’, ‘GZ18’) and non-sugarcane (CK) soils. Putative allelochems. of the rhizospheric soil extracts were then identified via GC-MS. In comparison with CK, high concentration water extracts inhibit lettuce growth whereas low concentration extracts promote growth. Inhibitory effects of rhizospheric soil water extracts of ratoon sugarcane are higher than that of newly planted sugarcane. Rhizospheric soil extracts from newly planted and ratoon sugarcanes by weak polarity petroleum ether and ether solvents promote lettuce growth. The reverse is true for extracts by medium polarity chloroform and strong polarity methanol. Further allelochem. anal. suggests that inhibitory effect of methanol extract is the strongest. Allelopathic effect of rhizospheric soil of ‘GZ18’ is higher than that of ‘FN28’ both by water extracting and polarity solvent extracting GC-MS anal. of methanol extract substances from ‘GZ18’ rhizospheric soils shows 54 compounds related with allelopathy, including acids, terpenoids, phenols, steroids and esters.

The volatile components of garlic were studied by GC-MS. The components in the cyclohexane, Et acetate and n-butanol extracts of the 95% alc. extract of garlic (Allium sativum) were compared with the volatile oil obtained by steam distillation from garlic. Qual. and quant. analyses were carried out by GC-MS (gas chromatog.-mass spectrometry). From the cyclohexane extraction, 112 components were detected and 38 compounds were identified, accounting for 80.08% of the cyclohexane extraction From the Et acetate extraction, 86 components were detected and 26 compounds were identified, accounting for 56.70% of the Et acetate extraction From the n-butanol extraction, no volatile component was detected by GC-MS. From the volatile oil obtained by steam distillation, 109 components were detected and 29 compounds were identified, accounting for 83.58% of the total volatile oil. The cyclohexane extraction and the Et acetate extraction of the 95% ethanol extract of garlic and the volatile oil were dominated by organosulfur components. According to the analyses of the cyclohexane extraction and the Et acetate extraction of the 95% ethanol extract of garlic, the contents of ajoene in the crude drug were 0.00395% and 0.00145%, resp. The content of ajoene in garlic was 0.00540%. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Synthetic Route of C9H16O4).

Long term exposure to virgin and recycled ldpe microplastics induced minor effects in the freshwater and terrestrial crustaceans Daphnia magna and Porcellio scaber was written by Kokalj, Anita Jemec;Dolar, Andraz;Titova, Jelizaveta;Visnapuu, Meeri;Skrlep, Luka;Drobne, Damjana;Vija, Heiki;Kisand, Vambola;Heinlaan, Margit. And the article was included in Polymers (Basel, Switzerland) in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:

The effects of microplastics (MP) are extensively studied, yet hazard data from long-term exposure studies are scarce. Moreover, for sustainable circular use in the future, knowledge on the biol. impact of recycled plastics is essential. The aim of this study was to provide long-term toxicity data of virgin vs recycled (mech. recycling) low d. polyethylene (LDPE) for two commonly used ecotoxicity models, the freshwater crustacean Daphnia magna and the terrestrial crustacean Porcellio scaber. LDPE MP was tested as fragments of 39.8 ± 8.82 μm (virgin) and 205 ± 144 μm (recycled) at chronic exposure levels of 1-100 mg LDPE/L (D. magna) and 0.2-15 g LDPE/kg soil (P. scaber). Mortality, reproduction, body length, total lipid content, feeding and immune response were evaluated. With the exception of very low inconsistent offspring mortality at 10 mg/L and 100 mg/L of recycled LDPE, no MP exposure-related adverse effects were recorded for D. magna. For P. scaber, increased feeding on non-contaminated leaves was observed for virgin LDPE at 5 g/kg and 15 g/kg. In addition, both LDPE induced a slight immune response at 5 g/kg and 15 g/kg with more parameters altered for virgin LDPE. Our results indicated different sublethal responses upon exposure to recycled compared to virgin LDPE MP. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Category: esters-buliding-blocks).
