Abstract
The yield of acetyl chloride from the reaction between acetic anhydride and hydrogen chloride is increased by withdrawing acetyl chloride, optionally together with at least some of the acetic acid by-product, from the reaction mixture as the reaction proceeds and recycling the remainder of the reaction mixture to the reactor for reaction with additional hydrogen chloride.
