| | CELLULOSE ACETATE Usage And Synthesis |
| Chemical Properties | white fine crystalline powder | | Uses | Excipient | | Preparation | Cellulose acetate is prepared by hydrolyzing the triester to remove some of the acetyl groups; the plastic-grade resin contains 38-40% acetyl. The propionate and butyrate esters are made by substituting propionic acid and its anhydride (or butyric acid and its anhydride) for some of the acetic acid and acetic anhydride. Plastic grades of cellulose-acetate–propionate resin contain 39-47% propionyl and 2-9% acetyl; cellulose-acetate–butyrate resins contain 26-39% butyryl and 12-15% acetyl.
These cellulose esters form tough, strong, stiff, hard plastics with almost unlimited color possibilities. Articles made from these plastics have a high gloss and are suitable for use in contact with food. |
