Zusammenfassung:The invention relates to a method for producing alkenyl succinic anhydrides of formula (1), in which R represents a C4 to C250 alkylene radical that can be linear or branched. The method involves the reaction of maleic acid, maleic anhydride, fumaric acid or esters thereof and an alkene which contains 4-250 carbon atoms at from 150 to 250° C. in the presence of a synergistic mixture of a primary antioxidant, a secondary antioxidant, and a metal deactivator.
