FIELD: chemistry.
SUBSTANCE: method of producing N-methyl-para-anisidine involves N-alkylation of para-anisidine and/or para-nitroanisole with methanol in vapour phase on a dehydrogenating copper-chromium catalyst at temperature of 180-260°C and atmospheric pressure, followed by separation of products by rectification. The invention also relates to a method of producing N-methyl-para-anisidine by N-alkylation of para-nitroanisole and/or para-anisidine with methanol in vapour phase at temperature of 180-260°C and atmospheric pressure, followed by separation of products by rectification on a dehydrogenating catalyst of the following composition: CuO - 25%; ZnO - 25%; CaO - 5%; Al2O3 - the balance or CuO - 35-45%; ZnO - 25-35%; NiO - 3-8%; Al2O3 - the balance.
EFFECT: obtaining N-methyl-para-anisidine with high purity and high output, which enables highly profitable, large-tonnage production.
