Daniel THIÉBAUT: Research and Development Manager Acetex Chimie
INTRODUCTION
Update of the Rhône-Poulenc text published in 1988 in this treatise
Acetic anhydride (figure 1 ), first synthesized in 1852 by C. Gerhardt, is the most widely used of the organic anhydrides.
The advent of acetate textile fibers gave it considerable importance in the early 1920s. Today, it is still mainly used as an acetylating agent in the manufacture of cellulose acetate. In order to recycle by-product acetic acid, virtually all acetic anhydride production processes use acetic acid as a raw material (ketene and Eastman processes). BP Chemicals, which is not involved in the manufacture of cellulose acetate, uses methanol and carbon monoxide as raw materials.
