cellulose triacetate

Cellulose triacetate is a synthetic compound derived from cellulose, a natural polymer found in plants. It is created by replacing the hydroxyl groups in cellulose with acetyl groups, making it soluble in certain solvents and allowing it to be processed into various forms.12

This process results in a high-melting, crystalline substance. When partially reversed through hydrolysis, it forms cellulose diacetate, which is soluble in cheaper solvents like acetone.12

Historically, cellulose acetate was developed as an alternative to the flammable cellulose nitrate. It was used to create nonflammable coatings for airplane wings during World War I. Later, it was commercialized as acetate fibers (rayon) for textiles and as a plastic for items like tool handles and photographic film. While its use in some applications has decreased due to competition from newer materials like polyester, it remains relevant for certain textiles and cigarette filters.12
