Triacetin (MF: C₉H₁₄O₆, MW: 218.2) is an ester compound produced by esterification of glycerol with acetic acid (or acetic anhydride). Its molecular structure contains three acetyl groups (-OOCCH₃), endowing it with both the stability of esters and the solubility of polar groups. It exhibits good thermal stability, decomposing completely only above 300°C, and is readily biodegradable by microorganisms, making it an environmentally friendly compound. It is widely used in tobacco, food, cosmetics, pharmaceuticals, and other industries.
