The economic development of any country is appreciably affected by the extensive use of rapidly depleting fossil resources. Identifying new, renewable based energy resource is of vital importance and is a global requirement too. This study focuses attention on the introduction of a new biodiesel resource Manilkara zapota seed oil, production and characterization of biodiesel from M. zapota seed oil. The raw oil is extracted from the seed by a mech. expeller. The composition of fatty acids and physicochem. properties of the raw oil have been estimated The suitability of M. zapota seed oil for biodiesel production was studied based on its chem. structure and physicochem. properties. Me ester was produced from the raw M. zapota seed oil using transesterification process using an alk. catalyst. The composition of fatty acids and physicochem. properties of the biodiesel derived have been estimated and compared with EN14214 biodiesel standards The new biodiesel M. zapota Me ester meets the EN14214 biodiesel standards and could be a reliable substitute to diesel in diesel engine applications. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Related Products of 1731-94-8).

Methyl nonadecanoate (cas: 1731-94-8) 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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.

A chemolithotrophic bacterium, Serratia sp. ISTD04, enriched in the chemostat in presence of sodium bicarbonate as sole carbon source was evaluated for potential of carbon dioxide (CO₂) sequestration and biofuel production CO₂ sequestration efficiency of the bacterium was determined by enzymic activity of carbonic anhydrase and ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). Further, Western blot anal. confirmed presence of RuBisCO. The bacterium produced 0.487 and 0.647 mg mg^-1 per unit cell dry weight of hydrocarbons and lipids resp. The hydrocarbons were within the range of C₁₃-C₂₄ making it equivalent to light oil. GC-MS anal. of lipids produced by the bacterium indicated presence of C₁₅-C₂₀ organic compounds that made it potential source of biodiesel after transesterification. GC-MS, FTIR and NMR spectroscopic characterization of the fatty acid Me esters revealed the presence of 55% and 45% of unsaturated and saturated organic compounds resp., thus making it a balanced biodiesel composition This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Quality Control of Methyl nonadecanoate).

Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Quality Control of Methyl nonadecanoate

The aim is to optimize the extraction process of tilapia fish head oil which is extracted by supercritical CO₂(SC-CO₂) from tilapia fish head. The signal factors were chosen by single-factor experiments and the optimal extraction conditions of tilapia fish oil by SC-CO₂ were optimized by response surface method. Then, the quality and fatty acid composition of tilapia fish head oil were analyzed. The results showed that the optimum conditions were: extraction pressure 36 MPa, extraction temperature 41°C and extraction time 3.1 h, which were better than cooking method, alkali hydrolysis method and enzymic method. The extraction rate under the optimal extraction condition by SC-CO₂ was 79.5%, and the iodine value, POV and acid value were 5.36±0.15 mg/kg, 4.27±0.33 mmol/kg and 139.0±8.9 g/100 g resp. The contents of saturated fatty acid(SFA), mono-unsaturated fatty acid(MUFA) and poly-unsaturated fatty acid(PUFA) were 27.85%, 41.74% and 30.41% resp. The tilapia fish head oil was rich in fatty acid, which indicated excellent nutritional value and functionality. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Related Products of 1731-94-8).

Methyl nonadecanoate (cas: 1731-94-8) 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 1731-94-8

And the article was included in Beilstein Journal of Organic Chemistry in 2016.Electric Literature of C20H40O2 The following contents are mentioned in the article:

The thermal and oxidative stability of Atlantic salmon oil (Salmo salar L.) as well as its β-cyclodextrin (β-CD) complexation ability has been verified for the first time. The main omega-3 fatty acids, EPA and DHA, were significantly degraded, even at 50 °C. Their relative concentrations decrease from 6.1% for EPA and 4.1% for DHA to 1.7% and 1.5% after degradation at 150 °C, resp. On the other hand, the relative concentrations of monounsaturated and saturated fatty acids remained constant or slightly increased by a few percent after degradation (e.g., from 10.7% to 12.9% for palmitic acid). Co-crystallization of ASO with β-CD at a host-guest ratio of 1:1 and 3:1 from an ethanol-water mixture and kneading methods has been used for the preparation of β-CD/ASO complexes. The anal. of the complexes by thermogravimetry, differential scanning calorimetry (DSC), and Karl Fischer titration (KFT) as well as the decrease of the “strongly-retained” water content confirm the formation of the inclusion compound Furthermore, the DSC parameters correlate well with the KFT kinetic data for β-CD/ASO complexes. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Electric Literature of C20H40O2).

Methyl nonadecanoate (cas: 1731-94-8) 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. 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.Electric Literature of C20H40O2

The researches on the stability of the compound system and the strong base, wastage of the agents in the oil phase and effects of the alkali, surfactant and polymer on the lactescence stability are conducted through collecting and analyzing the crude oils from the target layers of Lamadian, Saertu, Xingshugang Oilfields and so on. The study results show that the crude oil from Lamadian Oilfield has the characteristics of rather higher viscosity, higher paraffin content and higher gel content, and moreover the more kinds and quantities of the acid active components. The lactescence stability is pretty, higher and the wastage of the alkali in the oil phase is larger; with the higher content of the heavy components and wider range of the carbon chains, the wastage of the heavy alkyl benzene sulfonate surfactant in the crude oil is larger and the stability of the lactescence is higher; the single-base liquid acts with the oil and generates W/O-type emulsion, while the binary composite system of “alkali/surfactant” and ternary compound system of “alkali/surfactant/polymer” produce O/W-type emulsion.

Dynamics in nutrients, sterols and total flavonoid content during processing of the edible Long-Horned grasshopper (Ruspolia differens Serville) for food was written by Ochieng, Brian O.;Anyango, Joseph O.;Nduko, John M.;Cheseto, Xavier;Mudalungu, Cynthia M.;Khamis, Fathiya M.;Ghemoh, Changeh J.;Egonyu, Peter J.;Subramanian, Sevgan;Nakimbugwe, Dorothy;Ssepuuya, Geoffrey;Tanga, Chrysantus M.. And the article was included in Food Chemistry in 2022.HPLC of Formula: 1731-94-8 The following contents are mentioned in the article:

Long-horned grasshopper (Ruspolia differens Serville) is a tasty delicacy in over 20 African countries. This study evaluated the impact of diverse post-harvest thermal treatment (blanching, boiling, toasting, and deep-frying) on the nutrients, total flavonoid content and sterols preservation of R. differens products. Crude protein, ash, and fiber of R. differens was drastically reduced by deep-frying technique. There was increase in Omega-3 (α-linolenic acid), Omega-6 fatty acid (linoleic and arachidonic acids) and sterols [(22Z)-27-Norergosta-5,22-dien-3β-ol, cholesterol, campesterol, cholest-4-ene-3-one and β-sitosterol] and flavonoids (2-3 folds) during blanching compared to other techniques. The iron and zinc content increased significantly in blanched and boiled products of R. differens. Thus, losses of nutrients, total flavonoid content and sterols during processing of R. differens for food can be mitigated by employing blanching technique, which is cheaper and least time-consuming. The implications of these dietary and therapeutic compounds on human nutrition and health are discussed. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8HPLC of Formula: 1731-94-8).

And the article was included in Bioresource Technology in 2014.SDS of cas: 1731-94-8 The following contents are mentioned in the article:

Porous delignified cellulose (or tubular cellulose, abbr. TC) from Indian Mango (Mangifera indica) and Sal (Shorea robusta) wood and Rice husk, and TC/Ca-alginate/polylactic acid composites, were used as Lactobacillus bulgaricus immobilization carriers leading to improvements in lactic acid fermentation of cheese whey and synthetic lactose media, compared to free cells. Specifically, shorter fermentation rates, higher lactic acid yields (g/g sugar utilized) and productivities (g/L d), and higher amounts of volatile byproducts were achieved, while no significant differences were observed on the performance of the different immobilized biocatalysts. The proposed biocatalysts are of food grade purity, cheap and easy to prepare, and they are attractive for bioprocess development based on immobilized cells. Such composite biocatalysts may be used for the co-immobilization of different microorganisms or enzymes (in sep. layers of the biocatalyst), to efficiently conduct different types of fermentations in the same bioreactor, avoiding inhibition problems of chem. or biol. (competition) nature. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8SDS of cas: 1731-94-8).

Methyl nonadecanoate (cas: 1731-94-8) 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. 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.

Effect of crude oil composition on ternary composite alkali-surfactant-polymer flooding was written by Sun, Zhe;Sun, Xuefa;Lu, Xiangguo;Chen, Xin;Yu, Qin;Tian, Chunyu. And the article was included in Shiyou Huagong in 2016.Reference of 1731-94-8 The following contents are mentioned in the article:

The interactions between oil/water samples from different districts in Daqing oilfield with ternary composite alkali-surfactant-polymer (ASP) system were studied. The effects of the crude oil compositions on the crude oil production increment with ASP system and the properties of the produced fluid were studied. The oil/water samples, extracted active ingredients, raffinate oil and sulfur content in the oil phase were analyzed by means of FTIR, GC-MS and XRF. It was showed that, the characteristic peaks of the active ingredients in the oil/water samples accorded with the features of typical saturated monocarboxylic acids (fatty acids and naphthenic acids). The concentration of n-alkanes with heavy component in the raffinate oil from the Lamadian oil/water sample was higher, and its composition was closer to that of the surfactant (heavy alkylbenzene sulfonates). It was indicated that, the interfacial tensions between the ASP system and the active ingredients in the oil/water samples or the raffinate oil were high, but there were ultra-low interfacial tensions between the ASP system and the crude oils. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Reference of 1731-94-8).

Methyl nonadecanoate (cas: 1731-94-8) 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. 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.Reference of 1731-94-8
