Method for synthesizing 1, 3-adamantane diamine

Abstract

The invention discloses a method for synthesizing 1, 3-adamantane diamine. The 1, 3-adamantane diamine synthesized by the method is prepared by the following steps of: performing amination on 1, 3-dibromoadamantane and urea in a high boiling point solvent; and performing separated purification through acidification, neutralization and extraction. The method particularly comprises the following steps of: mixing the 1,3-dibromoadamantane and the urea uniformly according to the molar ratio of the 1,3-dibromoadamantane to the urea of 1:2-10; adding the high boiling point solvent; heating the mixture to a preset temperature in an oil bath and reacting under stirring; after the reaction is finished, cooling to 50 DEG C; adding hydrochloric acid and stirring to dissolve the product; filtering to remove insoluble impurities; adding sodium hydroxide solution into filtrate to neutralize; adding an excessive organic solvent to perform extraction; distilling the obtained extract liquid under reduced pressure to remove the solvent; and performing vacuum drying to obtain the product 1,3-adamantane diamine. The method has the advantages of short reaction route, simpleness and convenience in operation, mild condition, clean and environmentally-friendly process, high product yield and the like.
