Production of mono-N-alkyl-dinitroalkylanilines and N-alkyl- dinitroaniline derivatives

摘要

This invention relates to a process for producing mono- and di- N- alkyl-dinitroalkylaniline or dinitroaniline derivative 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 acetic acid alkylanisole or anisole derivative which is followed by reaction with an amine. Acetic acid by-product produced during nitration is recycled by converting back to acetic anhydride.
