Article abstract of DOI:10.1016/S0040-4039(00)85100-X

A solid-phase copolymer of 4-vinylpyridine is shown to be a highly effective reagent/catalyst for the synthesis of acid anhydrides from mixtures containing equimolar quantities of carboxylic acid and acid chlorides.The process may be carried out in batch or column mode.
