Abstract: 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.

Abstract: 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 <2:1.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A fatty acid alkyl ester of the general formula I: and acrolein are prepared by reacting a triglyceride of the general formula II: wherein a) the triglyceride is reacted using an alcohol R?—OH in the presence of a catalyst to give said fatty acid alkyl ester and glycerol; and b) the glycerol is dehydrated catalytically to acrolein, wherein R is R1, R2 and R3, and R1, R2 and R3 are all the same or some are the same or all are different and are each a straight-chain or branched, and optionally mono- or polyunsaturated C10-C30-alkyl radical, and R? is a C1-C10-alkyl radical or a C3-C6-cycloalkyl radical.
