Catalyst for methylmercaptane preparation from methanol and hydrogen sulfide |
| abstract |
FIELD: chemistry. ^ SUBSTANCE: invention refers to methylmercaptane synthesis prepared from aluminium oxide, alkali metal wolframate and at least one of ammonium salt containing sulphur or nitrogen with catalyst pH in water suspension 10% being 5.0 - 9.7. The method of methylmercaptanes preparation from methanol and hydrogen sulfide using said catalyst is described also. ^ EFFECT: enhancing of catalyst activity and selectivity particularly at low hydrogen sulfide/methanol ratios. ^ 6 cl, 2 tbl, 4 ex |
