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.
Claims4
In a process for preparing acetyl chloride by reacting acetic anhydride with hydrogen chloride to form a mixture of acetyl chloride, acetic acid, acetic anhydride, and hydrogen chloride in a reactor, the improvement which comprises improving the yield of acetyl chloride by withdrawing acetyl chloride from the mixture as the reaction proceeds and recycling the remainder of the mixture to the reactor for reaction with additional hydrogen chloride.
