In addition, it has an acceptable fiber length and specific gravity, which is comparable to that of hardwoods (Hindi et al. 2010). Cellulose derivatives have gained attention worldwide due to their abundance and Cellulose acetate film, or safety film, is used in photography as a base material for photographic emulsions.It was introduced in the early 20th century by film manufacturers and intended as a safe film base replacement for unstable and highly flammable nitrate film..

Acetylation converts hydroxyl groups in cellulose to acetyl groups, which renders the cellulose polymer much more soluble in organic solvents. The cellulose acetate is dissolved in a mixture of dichloromethane and methanol for spinning. Cellulose triacetate - MISC, GMP, Fixing agent for the immobilization of lactase for use in reducing the lactose content of milk - 173.357 FDA Center for Food Safety and Applied Nutrition (CFSAN) 8 Pharmacology and Biochemistry In the hydrolysis step the cellulose triacetate is hydrolyzed to remove enough of the acetyl groups to result in an average number of acetyl groups per ring of about 2.4.
