What is triacetin made from?
Triacetin was prepared in the 19th century from glycerol and acetic acid. Its synthesis from acetic anhydride and glycerol is simple and inexpensive. This synthesis has been conducted with catalytic sodium hydroxide and microwave irradiation to give a 99% yield of triacetin.
Is triacetin flammable?
Combustible. NO open flames. Use water spray, powder, alcohol-resistant foam, carbon dioxide.
How is Triacetin manufactured?
Production Process Triacetin is produced from a multi-stage reaction sequence involving glycerine, acetic acid and acetic anhydride as raw materials. In the first reaction, glycerine is esterified with acetic acid. In this first stage, the conversion is to mono1 di-acetin.
Is triacetin soluble in water?

Is triacetin biodegradable?
Incomplete biodegradation was observed for test items with 20% triacetin or with 30% phthalate. After 46 days of incubation, the test samples with 30% plasticizer based on triacetin or triacetin-diacetin were completely biodegraded.
