}}
Cellulose triacetate, also known simply as triacetate, CTA and TAC, is manufactured from cellulose and a source of acetate esters, typically acetic anhydride. Triacetate is typically used for the creation of fibres and film base.
It is similar chemically to cellulose acetate, with the distinguishing characteristics being that in triacetate, according to the Federal Trade Commission definition, at least "92 percent of the hydroxyl groups are acetylated." During the manufacture of triacetate the cellulose is completely acetylated whereas in regular cellulose acetate or cellulose diacetate, it is only partially acetylated. Triacetate is significantly more heat resistant than cellulose acetate.
==History==
Triacetate, whose chemical equation is ()n, was first produced commercially in the U.S. in 1954 by Celanese Corporation (). Mitsubishi Rayon Co., Ltd., is the only company that still produces the fiber. Eastman Kodak formerly manufactured cellulose triacetate. They discontinued this product on March 15, 2007. In 2010 Eastman Chemical announced a 70% increase in cellulose triacetate output at its Kingsport, TN manufacturing site in late 2010 to supply increasing demand for the chemical's use as an intermediate in the production of polarized films for liquid crystal displays (LCD)s.
