    摘要: A process for the production of allyl succinic anhydride comprising reacting a mixture of propene with maleic anhydride in the presence of a catalyst comprised of an alkyl tin chloride as provided. The process can be run efficiently at temperatures below about 200° C. without and the formation of polymer or decomposition by-products.
