FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing alkyl mercaptan by reacting an aliphatic alcohol, which is C1-C3 an aliphatic alcohol with hydrogen sulphide in the presence of a heterogeneous catalyst with periodically varying reaction temperatures at the stages.
EFFECT: technical result is increased selectivity of methyl mercaptan compared to its selectivity at the beginning of the reaction.
