Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a thiol, a thioether, and a disulfide, by reacting an olefin with hydrogen sulfide.
SOLUTION: This method for preparing a sulfur-containing compound expressed by general formula I (Q is -S- or -S-S-; and R
1 is H or a 1-30C saturated or unsaturated straight-chain or branched-chain alkyl and R
2 is H or a 1-30C saturated or unsaturated straight-chain or branched-chain alkyl, provided that R
1 and R
2 are not allowed to be H at the same time) comprises reacting a mixed gas stream containing the hydrogen sulfide with the 1-30C straight-chain or branched-chain olefin by using, or not using, oxygen, wherein reaction is conducted at a pressure of 2-325 bar in the presence of water and carbon dioxide.

Abstract: A method for the production of aromatic di-isocyanates (I) by gas-phase reaction of phosgene with diamines involves carrying out the reaction in a reaction zone under a pressure of more than 3 bar and less than 20 bar. An Independent claim is also included for a production unit for this process, in which the ratio of production capacity to phosgene hold-up is more than 3200 tonnes di-isocyanate per annum/kg phosgene.

Abstract: The present invention relates to a continuous process for preparing isocyanates by reacting primary amines with phosgene, wherein the reaction is carried out in a cascade of at least two tube reactors and the gas phase formed in the reaction is separated off in a phase separator after each reactor and only the liquid phase is passed to the next reactor or to product purification and the reaction volume of the first tube reactor is only a fraction of the total reaction volume.

Abstract: The invention relates to a method for producing isocyanates by reacting primary amines with phosgene in the gaseous phase. Said method is characterized in that the reaction of amine and phosgene occurs in a reaction channel, the internal dimensions of which have a width/height ratio of at least 2/1.
