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.
摘要翻译： 从甲硫醇的催化合成中分离产物气体混合物的方法。 由于改进了产物气体混合物与其组分的分离，在排放惰性气体方面比在已知方法中更少的硫化氢和甲基硫醇就会减少。 惰性气体可以在没有废气的后处理的情况下燃烧。 同样，排出的工艺水较少被多硫化物污染。

摘要： The invention relates to a process for separating acrolein from the process gas of a heterogeneously catalyzed oxidation of propene by means of atmospheric oxygen, wherein high boilers (including acrylic acid) are firstly separated off from the process gas by means of quenching and technical-grade acrolein having small proportions of low boilers is then obtained by means of absorption and subsequent distillation. Small amounts of a solvent by means of which, in particular, oligomers formed are separated off and the tendency for foam to be formed in the apparatuses or columns is reduced is added in the columns and heat exchangers in the work-up process. The solvent is, according to the invention, separated off and recycled in the form of an organic phase in-situ within the existing process.
