FIELD: chemistry.
SUBSTANCE: catalyst contains zinc chloride and carrier - porous granulated carbon-carbonic composition material based on pyrocarbon and nanodispersed carbon with specific surface by "БЭТ" 350-650 m2/g and total pore volume by water 0.55-0.85 cm3/g. Described is method of preparation of catalyst described above, which is prepared by impregnating carrier with water or hydrochloric acid solution of zinc chloride in two stages: zinc chloride sorption by carrier from water solution at temperature 15-25°C and evaporation of remaining part of solution at temperature 80-100°C. Also described is process on obtaining methylchloride by catalytic hydrochlorating of methanol, which is carried out in continuous reactor at temperature 140-200°C and contact time 0.6-1.11 s in presence of described above catalyst.
EFFECT: complete methanol conversion and complete selectivity to methylchloride.
