Alkenyl succinic anhydrides having a decreased amount of tar and color bodies are made by the reaction of an olefin with maleic anhydride in the presence of an arylfluorophosphite (e.g. 2,2'-ethylidenebis(4,6-di-tert-butylphenyl) fluorophosphite) and optionally a hindered phenolic antioxidant such as 2,4,6-tri(3,5-di-tert-butyl-4-hydroxybenzyl) mesitylene.
