Description

Cellulose triacetate is a compound produced from a source of cellulose and acetate (usually acetic anhydride). Triacetates are commonly used in the manufacture of fibers and film bases. It is chemically similar to cellulose acetate. Its distinguishing feature is that in triacetate, at least 92% of the hydroxyl groups are acetylated. During the production of triacetate, cellulose is fully acetylated; in normal cellulose acetate or cellulose diacetate, it is only partially acetylated. The heat resistance of triacetate is significantly higher than that of cellulose acetate.
