Abstract
FIELD: catalytic chemistry. SUBSTANCE: additional component is added to the catalyst for synthesis of methylmercaptan from methyl alcohol and hydrogen sulfide resulted in the following catalyst composition: 12 wt % tungsten potassium, 2-3.5 wt % boron oxide, the rest being aluminium oxide. The catalyst is prepared by mixing aqueous solutions of boric acid and potassium tungstate with aluminium hydroxide, or by mixing aqueous solutions of boric acid and potassium tungstate with aluminium hydroxide, or by mixing aqueous solution of boric acid with a mixture of dry aluminium hydroxide and potassium tungstate followed by heat treatment at 380-390 C, or by mixing boric acid with aluminium hydroxide followed by calcination at 490-500 C, impregnating potassium tungstate solution, drying and calcination at 380-390 C. Testing of the catalyst was carried out at hydrogen sulfide to methyl alcohol mole ratio 1.8:1 and at the temperature 320-375 C, the conditional contact time being 18-25 s. Catalyst productivity and selectivity in respect to methylmercaptan (11.2 mole/h per 1 l of catalyst and 95-97%, respectively) as compared to former data (4.7 and 91) is markedly improved. EFFECT: improved catalyst activity. 1 tbl
