The conversion of lignocellulose into a value-added chem. with high selectivity is of great significance but is a big challenge due to the structural diversities of biomass components. Here, we have reported an efficient approach for the one-step conversion of raw lignocellulose into di-Et maleate by the polyoxometalate ionic liquid [BSmim]CuPW₁₂O₄₀ in ethanol under mild conditions. The results reveal that all of the fractions in biomass, i.e., cellulose, lignin and hemicellulose, were simultaneously converted into di-Et maleate (DEM), achieving a 329.6 mg g^-1 yield and 70.3% selectivity from corn stalk. Importantly, the performance of the ionic liquid catalyst [BSmim]CuPW₁₂O₄₀ was nearly twice that of CuPW₁₂O₄₀, which can be attributed to the lower incorporation of the Cu2+ site in [BSmim]CuPW₁₂O₄₀. Hence, this process opens a promising route for producing bio-based bulk chems. from raw lignocellulose without any pretreatment. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Product Details of 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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.Product Details of 763-69-9

Identification of Trace Volatile Compounds in Freshly Distilled Calvados and Cognac Using Preparative Separations Coupled with Gas Chromatography-Mass Spectrometry was written by Ledauphin, Jerome;Saint-Clair, Jean-Francois;Lablanquie, Odile;Guichard, Hugues;Founier, Nicole;Guichard, Elisabeth;Barillier, Daniel. And the article was included in Journal of Agricultural and Food Chemistry in 2004.Synthetic Route of C7H14O3 The following contents are mentioned in the article:

GC-MS using both electron impact and chem. ionization detection modes led to the determination of the volatile composition of 2 samples of freshly distilled Cognac and 2 samples of freshly distilled Calvados. A total of 169 volatile compounds were directly identified in dichloromethane extracts obtained by liquid-liquid extraction Trace compounds present in both spirits were characterized with the help of preparative separations In a 1st step, groups of compounds were separated by preparative GC, and the fractions were analyzed on a polar stationary phase by GC-MS. In a 2nd step, silica gel fractionation was used to sep. them by polarity. In 331 compounds, of which 162 can be considered as trace compounds, were characterized in both freshly distilled Cognac and Calvados. Of these, 39 are common to both spirits; 30 are specific to Cognac with numerous hexenyl esters and norisoprenoidic derivatives, whereas 93 are specific to Calvados with compounds such as unsaturated alcs., phenolic derivatives, and unsaturated aldehydes. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Synthetic Route of C7H14O3).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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.Synthetic Route of C7H14O3

Sampling methods for the study of volatile profile of PDO wine vinegars. A comparison using multivariate data analysis was written by Rios-Reina, Rocio;Morales, M. Lourdes;Garcia-Gonzalez, Diego L.;Amigo, Jose M.;Callejon, Raquel M.. And the article was included in Food Research International in 2018.Application In Synthesis of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

High-quality wine vinegars have been registered in Spain under protected designation of origin (PDO): “Vinagre de Jerez”, “Vinagre de Condado de Huelva” and “Vinagre de Montilla-Moriles”. The raw material, production and aging processes determine their quality and their aromatic composition Vinegar volatile profile is usually analyzed by gas chromatog.-mass spectrometry (GC-MS), being necessary a previous extraction step. Thus, three different sampling methods (Headspace solid phase microextraction “HS-SPME”, Headspace stir bar sorptive extraction “HSSE” and Dynamic headspace extraction “DHS”) were studied for the anal. of the volatile composition of Spanish PDO wine vinegars. Multivariate curve resolution (MCR) was used to solve chromatog. problems, improving the results obtained. Principal component anal. (PCA) showed that not all the sampling methods were equally suitable for the characterization and differentiation between PDOs and categories, being HSSE the technique that made able the best vinegar characterization. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Application In Synthesis of Ethyl 3-ethoxypropanoate).

Experimental study of surface heating by a high speed exhaust plume was written by Kuo, Y. D.;Smith, N. S. A.;Honnery, D. R.. And the article was included in Experimental Thermal and Fluid Science in 2016.Product Details of 763-69-9 The following contents are mentioned in the article:

Airframe surface heating by gas turbine plume is an ongoing issue in aerospace applications. This paper presents the practicability of a smaller scale system based on a micro gas turbine which offers verisimilitude and realism to the actual airframe surface heating by a full scale engine exhaust plume flow. A thin flat plate made from 7075-T6 aluminum alloy was placed at X = 7D downstream of the nozzle exit of the gas turbine. Nozzle exit flow temperature ranged from 850 K to 920 K and Reynolds number over the sample plate ranged from 3.8 × 10⁴ to 2.6 × 10⁵. The average Nusselt number was found to be correlated to CRe^mPrⁿ with m = 0.42, n = 0.33, C = 0.094 for parallel plume flow over the sample plate at X = 7D and Z = 0D. It was also found that coefficient C can be scaled by velocity magnitude ratio with respect to the plume center if the sample was positioned away from the center of the jet plume. Heat transfer by IR radiation was found to be less than 2% compared to the overall heat flux. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Product Details of 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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.Product Details of 763-69-9

Volatile profile of Madeira wines submitted to traditional accelerated ageing was written by Pereira, Vanda;Cacho, Juan;Marques, Jose C.. And the article was included in Food Chemistry in 2014.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

The evolution of monovarietal fortified Madeira wines forced-aged by traditional thermal processing (estufagem) were studied in terms of volatiles. SPE extracts were analyzed by GC-MS before and after heating at 45°C for 3 mo (standard) and at 70°C for 1 mo (overheating). One hundred and ninety volatile compounds were identified, 53 of which were only encountered in baked wines. Most chem. families increased after standard heating, especially furans and esters, up to 61 and 3-fold, resp. On the contrary, alcs., acetates and fatty acids decreased after heating. Varietal aromas, such as Malvasia’s monoterpenic alcs. were not detected after baking. The accelerated aging favored the development of some volatiles previously reported as typical aromas of finest Madeira wines, particularly phenylacetaldeyde, β-damascenone and 5-ethoxymethylfurfural. Addnl., Et butyrate, Et 2-methylbutyrate, Et caproate, Et isovalerate, guaiacol, 5-hydroxymethylfurfural and γ-decalactone were also found as potential contributors to the global aroma of baked wines. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: Ethyl 3-ethoxypropanoate).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: Ethyl 3-ethoxypropanoate

Recommended Correlations for the Surface Tension of Aromatic, Polyfunctional, and Glyceride Esters was written by Mulero, A.;Cachadina, I.;Vegas, A.. And the article was included in Journal of Physical and Chemical Reference Data in 2022.Electric Literature of C7H14O3 The following contents are mentioned in the article:

Surface tension values for 79 esters, including aromatics, polyfunctional, and glycerides, have been compiled from databases, books, and papers in the literature. The data have been carefully screened, and finally, 1517 values were selected. Each fluid dataset has been fitted with the Guggenheim-Katayama correlation with two or four adjustable parameters. Recommended correlations are proposed for each ester, providing mean absolute deviations below 0.50 mN/m for 77 of them, mean absolute percentage deviations below 1.7% for 76 of them, and percentage deviations below 10%, except for four data out of the 59 selected for tricaprylin. The highest deviations found are due to the disagreement between the data obtained from different sources and not to an inadequate math. form of the correlation model. These correlations are added to the collection of those previously proposed for different fluids, including common substances, alcs., refrigerants, organic acids, n-alkanes, and 80 other esters.

Tuning the wettability and surface free energy of poly(vinylphenol) thin films by modulating hydrogen-bonding interactions was written by Wang, Chih-Feng;Ejeta, Dula Daksa;Wu, Jian-Yi;Kuo, Shiao-Wei;Lin, Ching-Hsuan;Lai, Juin-Yih. And the article was included in Polymers (Basel, Switzerland) in 2020.Reference of 763-69-9 The following contents are mentioned in the article:

The ability to tune the surface properties of a polymer film in a simple and effective manner is important for diverse biol., industrial, and environmental applications. In this work, we investigated whether or not the surface free energy of poly(vinyl phenol; PVPh) can be tuned by adjusting the casting solvent and the thermal treatment time, which alters the proportions of intraand intermol. hydrogen bonding interactions. Compared to the untreated sample, in THF system, the thermal treatment resulted in a lower proportion of intermol. hydrogen bonds and a concomitant decrease in the surface free energy (from 39.3 to 18.8 mJ/m2). In contrast, the thermal treatment in propylene glycol Me ether acetate (PGMEA) and ethyl-3-ethoxypropionate (EEP) systems increased the proportion of intermol. hydrogen bonds and the surface free energy of the polymer thin films, from 45.0 to 54.3 mJ/m2 for PGMEA and from 45.5 to 52.9 mJ/m2 for EEP. Controlling intermol. hydrogen-bonding interactions is a unique and easy method for tuning the surface free energies of polymer substances. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Reference of 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.

Durable siloxane-polyurethane coatings for mitigating freshwater mussel fouling was written by Galhenage, Teluka Pasan;Stafslien, Shane J.;Skaja, Allen;Webster, Dean C.. And the article was included in Biofouling in 2022.Synthetic Route of C7H14O3 The following contents are mentioned in the article:

Siloxane-polyurethane hybrid coatings were assessed for biofouling control caused by freshwater mussels. Invasive species such as zebra (Dreissena polymorpha) and quagga (Dreissena bugensis) mussels have rapidly spread through the waterways in the United States causing major concerns in reservoir infrastructure and freshwater lakes. Current coating solutions such as biocidal anti-fouling coatings are not suitable given the released biocides which may accumulate in reservoirs. Biocide free fouling release coatings based on silicone elastomers do not have adequate mech. durability. The siloxane-polyurethane (SiPU) coatings were evaluated using model organism laboratory assays and real-life performance was evaluated in the freshwater field environment. Two coating compositions displayed excellent performance in field trials for up to 2+ years. The surface anal. experiments of the coatings indicate that the morphol. of the coatings is affected by the formulations’ solvent choice. These coatings show great promise in mitigating biofouling predominated by freshwater mussels.
