Triacetin is an oily liquid. It is colorless, viscous, and almost odorless (little oily or rancid odor) and owns a high boiling point and a low melting point.

The molecular formula of triacetin is: C9H14O6.

Cas.-No.: 102-76-1

The production process of triacetin contains the following steps:

Glycerol reacts with acetic acid in a classic esterification reaction.
The generated product can then be purified, using e.g., subsequent vacuum distillation

Alternatively, Triacetin can be synthesized from acetic anhydride and glycerol in the presence of phosphoric acid or zinc chloride. In addition, triacetin is formed by acetylation of glycerol.
