摘　　要：以苯硫酚和碳酸乙烯酯为原料,1,5-二氮杂二环[4.3.0]壬-5-烯(DBN)为催化剂,合成了2-苯硫基乙醇。研究了催化剂种类及其物质的量、反应时间、反应温度等条件对反应的影响。结果表明,在DBN为催化剂、n(苯硫酚)/n(DBN)=100、反应时间为10 min、反应温度为50℃时,2-苯硫基乙醇的转化率达到90%以上;当反应温度为90℃时,可获得100%的转化率,该合成路线催化剂的选择性均为100%。根据软硬酸碱理论对反应机理进行了探讨。2-Phenylthioethanol was synthesized from thiophenol and ethylene carbonate using 1,5-diazabicyclo[4.3.0]non-5-ene(DBN)as a catalyst.The effects of catalyst type and amount,reaction time and temperature on the reaction were studied.The results showed that,the conversion of 2-phenylthioethanol can reach more than 90%when the reaction temperature is 50℃and 100%conversion can be obtained when the reaction temperature is 90℃using DBN as the catalyst,n(thiophenol)/n(DBN)=100,the reaction time 10 min.The selectivity of the catalyst of the synthetic route is 100%The paper discusses the reaction mechanism according to the theory of soft and hard acid and alkali.
