The invention relates to a process for continuously preparing methyl mercaptan by reacting a mixture comprising carbon compounds with sulfur and hydrogen, wherein the carbon disulfide and hydrogen sulfide compounds which form are subsequently converted to methyl mercaptan.

Process for continuously preparing methyl mercaptan from carbon compounds, sulfur and hydrogen

The invention relates to a catalyst containing alkali tungstate for the synthesis of alkylmercaptanes from alkanols and hydrogen sulphide, in addition to a method for the production of said catalyst, wherein the molar ratio of alkali to tungstan is &#x3c;2:1.

Catalysts containing tungstate for the synthesis of alkyl mercaptan and method for the production thereof

Provided is a process for continuously preparing methyl mercaptan by reacting a reactant mixture comprising solid, liquid and/or gaseous carbon- and/or hydrogen-containing compounds with air or oxygen, and/or water and sulfur.

Process for continuously preparing methyl mercaptan from carbon- and hydrogen-containing compounds

The invention relates to a reaction vessel in which hydrogen sulphide is produced from sulphur and hydrogen, wherein the reaction vessel is partially or completely made up of a material which is resistant to the reaction mixture and its compounds and/or elements and which remains resistant even at high temperatures.

Production of hydrogen sulphide in a reaction vessel

The invention relates to a process for preparing alkyl mercaptans by catalytic gas phase reaction of alkanols and hydrogen sulphide over alkali metal tungstates, the reaction being performed in at least two successive reaction zones which contain catalysts of different activity and selectivity.
