Abstract
Abstract Symmetrical anhydrides are produced quickly and in high yield by treating mixtures of a carboxylic acid and one-half equivalent thionyl chloride in dichloromethane with a solid-state copolymer of 4-vinylpyridine. This conversion is accomplished equally well in batch or column mode.
