Technical Field

[0001] The utility model relates to the technical field of propyl mercaptan synthesis, in particular to a propyl mercaptan synthesis combined reaction device. Background Art

[0002] n-Propane mercaptan and isopropyl mercaptan are organic intermediates. n-Propane mercaptan is mainly used for the synthesis of pesticides, such as the synthetic insecticide propylphos, while isopropyl mercaptan is mainly used for the synthesis of spices. n-Propane mercaptan and isopropyl mercaptan can be catalytically reacted with hydrogen sulfide by n-propanol and isopropyl alcohol, respectively, to produce propylene at the same time. Propylene can also react with hydrogen sulfide to produce isopropyl mercaptan under certain conditions. The mixed gas of excess hydrogen sulfide and generated propylene in the existing propanethiol reaction device is difficult to recycle and can only be treated by incineration and other methods, resulting in an increase in the consumption quota of hydrogen sulfide and propanol.
