ABSTRACT:
Cellulose acetate is produced from methanol, carbon monoxide and cellulose in an integrated series of steps wherein acetic anhydride produced in a first step by the carbonylation of methyl acetate is used to acetylate cellulose to produce cellulose acetate and to co-produce acetic acid, the co-produced acetic acid is dehydrated and the dehydrated acetic acid reacted with methanol to produce methyl acetate which is then fed to the first step and carbonylated to produce additional quantities of acetic anhydride.
