| description | The invention relates to a phenthiol synthesis method, in particular to a method comprising the following steps that in a high-pressure reaction vessel, hydrogen sulfide takes a contact reaction with chlorobenzene in a supercritical state, wherein the mol ratio of the chlorobenzene to the hydrogen sulfide is 1:1 to 1:10, the reaction temperature is 100 DEG C to 200 DEG C, the reaction pressure is 9 to 25 MPa, and the reaction time is 1 to 10 hours; after the reaction is completed, water is used for washing a reaction mixture; an oil phase is collected; reduced pressure distillation is performed; fraction (10mmHg, 47 to 49 DEG C) is collected; the phenthiol is obtained.
本发明涉及合成苯硫酚的方法，具体涉及在高压反应器中，使硫化氢在超临界状态下与氯苯接触反应，氯苯与硫化氢的摩尔比为1∶1～1∶10，反应温度为100℃～200℃，反应压力为9～25MPa，反应时间为1～10小时，在反应结束后，用水洗涤反应混合物，收集油相，减压精馏，收集(10mmHg，47-49℃)馏分，即为得到苯硫酚。 |
