The volatile compounds of supple and mellow flavor type in Yanghe’s Lansejidian liquor were isolated and separated by liquid-liquid extraction (LLE) and fractionation. The total of 933 peak were detected, and 672 compounds were identified by gas chromatog.-mass spectrometry (GC-MS). Of these, 261 volatiles were unknown. These compounds were alcs., aldehydes, ketones, fatty acids, esters, aromatic compounds, phenols, sulfur-containing compounds, furans, epoxy compounds, acetals, pyrroles, pyridines, lactones, and terpenes. Lactones and terpenes were first detected in Chinese liquors. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Category: esters-buliding-blocks).
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. 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.Category: esters-buliding-blocks
