摘要： The present invention relates to a process of recovering monomeric esters of substituted or unsubstituted acrylic acid from polymer material having corresponding structural units by depolymerization by means of a fine-grained heat-transfer medium which is maintained above the depolymerization temperature of the polymer material. In a reactor, the polymer material is brought in contact with hot, mechanically fluidized heat-transfer medium. The resulting vapors are withdrawn and condensed, where the hot heat-transfer medium is continuously supplied at one end of the reactor, and cooled heat-transfer medium is discharged at the other end.

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.
