METHOD FOR PRODUCING ALKENYL SUCCINIC ANHYDRIDES.

摘要

The invention relates to a method for producing alkenyl succinic anhydrides offormula (I), in which R represents a C4 to C250 alkylene radicalthat can be linear or branched. The method involves the reaction of maleic anhydrideand of an alkene, which contains 4 250 carbon atoms at 150 to 250 C in thepresence of a synergistic mixture consisting of a primary antioxidant, a peroxidedecomposer and of a metal deactivator.
