Abstract

Procedure for the dehydration of maleic acid, which comprises heating this acid in an evaporator in which it circulates, at a temperature sufficient to cause the formation of anhydride, characterized in that the dehydration is carried out in the presence of a liquid with a boiling point higher than that of maleic anhydride.
