ABSTRACT:
The present invention relates to a process for preparing sulfur-containing compounds of the general formula Iin which Q, R1and R2are each independently defined as follows:Q: —S— or —S—S—,R1: hydrogen or saturated or unsaturated, linear or branched C1-C30-alkyl radical,R2: hydrogen or saturated or unsaturated, linear or branched C1-C30-alkyl radical,where R1and R2are not simultaneously hydrogen, by reacting a mixed gas stream comprising hydrogen sulfide, with or without oxygen, with linear or branched C1-C30-olefins, which comprises carrying out the reaction in the presence of water and carbon dioxide at a pressure of from 2 to 325 bar.
