Method for preparing butane tetracarboxylic dianhydride

The invention discloses a method for preparing butane tetracarboxylic dianhydride, and belongs to the field of fine chemical preparation methods. The method comprises the following steps: using maleicanhydride and 1,3-butadiene as starting materials to synthesize tetrahydrophthalic anhydride as an intermediate product through a 1,4-addition reaction in a high temperature molten state; subjectingtetrahydrophthalic anhydride to hydrolysis, ozone oxidation, hydrogen peroxide oxidation reaction to obtain butane tetracarboxylic acid as an intermediate product; using acetic anhydride or propionicanhydride as a dehydrating agent, and subjecting the butane tetracarboxylic acid to synthesize butane tetracarboxylic dianhydride through dehydration closed-ring. Compared with the traditional process, the method has the advantages of mild reaction conditions, high product purity, high yield, and no pollution, and is suitable for large-scale industrial production.
