Cellulose acetate(9004-35-7) is the acetate ester of cellulose.
Cellulose acetate(9004-35-7) is moldable, in contrast to cellulose nitrate, which is not. It, however, has poor resistance to moisture. To overcome this disadvantage, treating the cotton linters with a mixture of butyric acid, acetic acid, and acetic anhydride produces a mixed acetate-butyrate.

History
Uses
Cellulose acetate(9004-35-7) is used as a film base in photography, and as a component in some adhesives.
Cellulose acetate(9004-35-7) is also used as a synthetic fiber.
Production
There are several production methods for Cellulose acetate(9004-35-7):
1. Purified cellulose from wood pulp or cotton linters
2. Mixed with glacial acetic acid, acetic anhydride, and a catalyst
3. Aged 20 hours- partial hydrolysis occurs
4. Precipitated as acid-resin flakes
5. Flakes dissolved in acetone
6. Solution is filtered
7. Spinning solution extruded in column of warm air. Solvent recovered
8. Filaments are stretched and wound onto beams, cones, or bobbins ready for use
