FIELD: chemistry.
SUBSTANCE: invention claims catalyst based on copper-containing oxide compounds for obtaining N-methylaniline by alkylation of aniline with methanol containing copper and aluminium cations in composition of joint oxide compound. Oxide compounds of spinel structure, of the general formula (Cu1-xZnx)1+zAl2-yCryO4+z, where x=0÷0.5; y=0÷1.8, z=0-1, are used as joint oxide compound. Method of obtaining N-nethylaniline by alkylation of aniline with methanol is implemented in the presence of hydrogen at atmosphere pressure and high temperature on the catalyst described above.
EFFECT: reduced methanol expenditure per unit of target product, reduced generation of byproducts.
