Embodiment 1
[0081]At room temperature, take 5.51 parts of epoxycyclohexane with a purity of 98% and 2.1 parts of trimethylbenzyl ammonium hydroxide with a content of 40%, mix them thoroughly, and add 6.34 parts of cyclohexane with a purity of 98% dropwise under stirring. Benzyl mercaptan, the rate of addition is controlled within about 30 minutes. Stir at room temperature (25° C.) for 3 hours and let stand for 1 hour; wash with water and extract with ethyl acetate to obtain 2-(benzyl)mercaptocyclohexanol with a purity of 90.1%. The yield of 2-(benzyl)mercaptocyclohexanol The yield (based on benzyl mercaptan) was 95.63%.
Embodiment 2
[0083] Get 21.52 parts of sodium isobutyl xanthate with a purity of 89% and 12.28 parts of benzyl chloride with a purity of 97% and 16.04 parts of isobutanol at 50°C for 4 hours, cool to room temperature (25°C), and then use Add 7.5l parts of ethylamine aqueous solution (content is 65%~70%) to the constant pressure dropping funnel, after reacting for 2 hours, add 4.2 parts of trimethylbenzyl ammonium hydroxide with content of 40% and mix and stir, then dropwise add 12.68 Parts of epoxycyclohexane with a purity of 98% were reacted for 3 hours, allowed to stand for 1 hour, filtered through sodium chloride, and isobutyl ethylthiocarbamate was distilled at a temperature of 160°C under a pressure of 0.01MPa to obtain purity Be 91.78% isobutyl ethyl thiocarbamate, the yield of isobutyl ethyl thiocarbamate (based on benzyl chloride) is 93.47%, the yield of 2-(benzyl) mercaptocyclohexanol ( Based on benzyl chloride) was 91.42%.
Embodiment 3
[0085] Get 5.21 parts of sodium isopropyl xanthate with a purity of 91% and 4.94 parts of benzyl chloride with a purity of 97% and 4.01 parts of isobutanol at 50°C for 4 hours, cool to room temperature (25°C), and then use Add 1.38 parts of ethylamine aqueous solution (65% to 70% content) into the constant pressure dropping funnel, react for 2 hours, add 1.1 parts of trimethylbenzyl ammonium hydroxide with a content of 40% and mix and stir, then add 3.17 parts of Epoxycyclohexane with a purity of 98%, reacted for 3 hours, let it stand for 1 hour, filtered sodium chloride, and distilled isopropyl ethylthiocarbamate at a temperature of 160°C under a pressure of 0.01MPa to obtain a purity of 90.56 %, the yield of isopropyl ethylthiocarbamate (based on benzyl chloride) is 90.13%, and the yield of 2-(benzyl) mercaptocyclohexanol (based on benzyl chloride) is 91.06%.
