Abstract
A process for preparing N-alkyl substituted nitrophthalimide by the nitration of N-alkyl substituted phthalimide using only nitric acid, said nitric acid having a concentration of at least about 95%, and then recovering N-alkyl nitrophthalimide from the nitric acid solution.
Claims10
A process for producing a mixture which consists essentially of N-alkyl-3-nitrophthalimide and N-alkyl-4-nitrophthalimide, which consists essentially of (1) mixing an N-alkylphthalimide with a nitrating reagent which consists essentially of nitric acid having a concentration of at least about 95%, (2) reacting the mixture within a temperature range of from about -20.degree. C. to the boiling point of nitric acid and (3) thereafter recovering the N-alkyl-3-nitrophthalimide and the N-alkyl-4-nitrophthalimide.
