Triacetin synthesis
Webtriacetate (di- and triacetin), and glycerol diglycidyl ether fit this criteria as expressed by their high normal boiling points and relatively low toxicities, e.g. LD50 (Table 1). As previously mentioned, a solvent should facilitate the combination of reactants and catalysts, and as such, it should be able to dissolve solids, liquids, and gases. WebMar 30, 2024 · Due to more industrial applications and the demand for triacetin over mono and diacetins, several special methods have been described for its preparation at high yields [7,15]. These methods involve the acetylation of glycerol into monoacetin with acetic acid and the subsequent acetylation of monoacetin into di- and triacetin using acetic …
