Abstract: Disclosed herein is a process for purifying propylene oxide, including the steps of: (i) providing a stream S0 containing propylene oxide, acetonitrile, water, and an organic compound containing a carbonyl group —C(═O)—; and (ii) separating propylene oxide from the stream S0 by subjecting the stream S0 to distillation conditions in a distillation column to obtain a gaseous top stream S1c which is enriched in propylene oxide compared to the stream S0, a liquid bottoms stream S1a which is enriched in acetonitrile and water compared to the stream S0, and a side stream S1b containing propylene oxide which is enriched in the carbonyl compound compared to the stream S0.

Abstract: Preparing sulfur-containing compounds comprises reacting a mixed gas stream comprising hydrogen sulfide, optionally with oxygen, with linear or branched 1-30C olefins and carrying out the reaction in the presence of water and carbon dioxide at a pressure of 2-325 bar. Preparing sulfur-containing compounds of formula R 1>-Q-R 2> comprises reacting a mixed gas stream comprising hydrogen sulfide, optionally with oxygen, with linear or branched 1-30C olefins and carrying out the reaction in the presence of water and carbon dioxide at a pressure of 2-325 bar. Q : -S- or -S-S-; R 1>, R 2>H or optionally saturated, linear or branched 1-30C alkyl. R 1> and R 2> are not simultaneously H.
