Abstract

PURPOSE:To store a solution of a maleimide in acrylonitrile stably for a long period while maintaining the solution at low corrosive properties without precipitating insoluble substances, by controlling acid content in the solution of a maleimide in acrylonitrile in a fixed amount. CONSTITUTION:In storing a solution of a maleimide in acrylonitrile, acid content in the solution is adjusted to <=0.3wt.% based on the maleimide. The acid component existing in the maleimide is an acid derivative such as sulfuric acid or p-toluenesulfonic acid and the maleimide is sufficiently washed with water to remove the acid component. The maleimide is useful as a raw material for polymers, drugs and agricultural chemicals. Since a container made of a stainless steel is used as the storage container, cost of handling facilities is inexpensive and since a specific material is not required for tank lorries and tankers necessary for transportation of the solution, the solution can be inexpensively transported.
