| Abstract: | A new method that the compound N-hydroxyphthalimide was composed in the solvent 1-butyl-3-methylimidazoliumhexafluorophosphate was studied.Some experiments were done to confirm the better conditions of the reaction by altering the reaction time,temperature and mole ratio.When the mole ratio of hydroxylamine hydrochloride to phthalic anhydride was 1.1 in PF6,keeping at 130 ℃ for 2 h,the yield reached 89%.The method simplified the separation of products and achieved the synthesis by a better way. |
