摘要： A process for continuous production of methyl mercaptan by catalytic reaction of methanol and hydrogen sulfide. Significant improvements in the pretreatment of the feed gas mixture and in utilization of the heat of reaction and the heat content of the product gas mixture. The energy required to vaporize the methanol is derived partly from utilization of the heat of compression of the hydrogen sulfide gas and from the heat content of the product gas leaving the reactor. The heat of reaction is utilized to heat the feed gas mixture to the reaction temperature, with the help of an external gas heater.

摘要： A process for separating the product gas mixture from the catalytic synthesis of methyl mercaptan. Because of improved separation of the product gas mixture into its components, less hydrogen sulfide and methyl mercaptan are lost in discharging the inert gases than in the known process. The inert gases can be burned without after-treatment of the exhaust gas. Likewise, the process water that is discharged is less contaminated with polysulfides.

摘要： A catalyst for the synthesis of methyl mercaptan from hydrogen sulfide and methanol, as well as a process for preparing the catalyst. The catalyst contains active aluminum oxide on which 15% to 40% by weight cesium tungstate is deposited as the activator. The activator, cesium tungstate, gives an unexpected increase in activity and selectivity as compared with potassium tungstate, which is used exclusively at the present state of the art.

摘要： This invention relates to a process for the production of primary and/or secondary amines from oxo compounds by catalytic imination of the oxo compound with ammonia or a primary amine and subsequent hydrogenation. Imination proceeds according to the invention in the presence of a novel imination catalyst, namely an organopolysiloxane containing sulphonate groups. This imination catalyst is distinguished by elevated activity. The process is in particular suitable for the production of isophorone diamine from isophorone nitrile, wherein it has proved possible to reduce the content of secondary products and to increase yield.
