The present invention relates to catalysts for the synthesis of methylmercaptan which is used in the production of methionine, agricultural chemicals and other chemical compounds. The purpose of this invention is to increase the catalyst activity while maintaining a high selectivity for the methylmercaptan. To this end, the catalyst of the present invention includes the following components: a potassium compound consisting of potassium aluminate KAlO2; a tungsten compound consisting of tungsten amorphous oxide (YI) -WO3; and an aluminium oxide which has a transport pore volume of at least 0.06 cm<3>/g with a pore radius of between 70 and 100 nm and contains one element of the group comprising sodium, boron or a mixture thereof. The components of the catalyst are selected in the following amounts: from 7.0 to 12.1 wt.% of tungsten oxide (YI); from 6.0 to 10.0 wt.% of potassium aluminate; from 0.3 to 3.0 wt.% of boron and/or sodium oxide or a mixture thereof; the balance consisting of Al2O3.
