PRODUCTION OF MONO-N-ALKYL-DINITROALKYLANILINES AND N-ALKYL-DINITROANILINE DERIVATIVES

摘要

This invention relates to a process for producing mono-N-alkyl-dinitroalkylaniline or dinitroaniline derivatives and particularly N-sec-butyl-4-tert-butyl-2,6-dinitroaniline by methylation of an alkylphenol or phenol derivative followed by nitration of the resulting alkylanisole or anisole derivatives which is followed by reaction with a primary amine. Acetic acid by-product produced during nitration is recycled by converting back to acetic anhydride.
