The chem. composition of liquid products obtained from liquefaction of several agro-industrial wastes was analyzed and the effects of microwave treatments were investigated, evaluating changes in chem. composition, structure, and phys. properties, looking forward to exploring new utilization routes or processing paths for these liquid products. Gas chromatog.-mass spectrometry (GC-MS) showed that the chem. components of liquefied products can be divided into several groups: furans, alcs., and esters and acid derivatives The microwave evaluation showed that irradiation at constant power levels affects the compositions of liquefied products. Fourier transform IR (FT-IR) spectroscopic anal. showed increases in the absorption bands of carbonyl and CH groups, which suggests that microwaves induced more intensive oxidation of hydroxyl groups into carbonyl groups. Elemental anal. indicated higher carbon and lower oxygen contents and higher heat heating value (20 MJ/kg) in treated products with respect to untreated samples. The use of liquefied products as a new energy source has advantages such as their liquid state, convenient energy value, and renewability. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Quality Control of Ethyl 3-ethoxypropanoate).
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. 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 Ethyl 3-ethoxypropanoate
