Abstract

PURPOSE: To obtain a maleimide advantageously by using a catalyst which is composed of a solid carrier bearing an acid and/or a salt thereof with the stating amine to effect dehydrative ring closure of the maleinamide acid previously prepared from maleic anhydride and a primary amine in a solvent.
CONSTITUTION: When a maleinamide acid prepared from maleic anhydride and a primary amine is ring-closed by sehydration in an organic solvent to give a maleinimide which is useful as a starting substance of resins, medicines or agrochemicals, a catalyst which is prepared by depositing an acid such as sulfuric and/or a salt thereof with the starting amine on a solid carrier such as kieselguhr or silica gel is used to increase contact efficiency between the maleinamide acid and the catalyst to produced the subject compound in high yield inexpensively, safely and simple.
