DD254303A3 - METHOD FOR OBTAINING PHTHALIIDES OF ALKALINE METALS - Google Patents

Abstract

The process for obtaining phthalimides of the alkali metals consists in the interaction of phthalimide with an alcoholic solution of an alkali metal hydroxide and / or alkali metal alcoholate under vacuum at 50 ... 140C. The alcohol and water produced during the reaction are removed at a rate which ensures an alcohol concentration of 10 to 60% by mass in the reaction mass when the alcoholic solution is supplied.
