摘要:
采用固体偏钛酸为催化剂,催化水解环氧环己烷制备反-1,2-环己二醇,考察搅拌速率、反应时间、反应温度、物料摩尔比、催化剂的量及催化剂的重复性对水解反应的影响,并通过数字熔点测试仪和傅里叶变换红外光谱仪(FT-IR)对产物进行表征。结果表明:在搅拌速度为350 r/min,反应时间为1 h,反应温度为80 ℃,环氧环己烷与水的摩尔比为1:10,催化剂用量为1.8%时,产物的熔点为102.9~103.0 ℃,反-1,2-环己二醇的收率为98%左右。在优化条件下,催化剂重复使用5次,反-1,2-环己二醇的收率未有明显降低。
Abstract:
Hydrolysis of 1,2-epoxycyclohexane to trans-1,2-cyclohexanediol was catalyzed by metatitanic acid.The main factors,such as speed of agitation,reaction time,temperature,mole ratio of reactants, and catalyst dosage,were investigated.The product was characterized by digital melting point tester and Fourier transform infrared spectrometry(FT-IR).Under optimal reaction conditions:agitation speed of 350 r/min,reaction time of 1 h,the reaction temperature of 80 ℃,n(C6H10O):n(H2O)of 1:10 and mass faction of catalyst in reactant of 1.8%,the melting point of the product was 102.9-103.0 ℃.The yield of trans-1,2-cyclohexanediol was about 98%.The catalyst still had high activity and selectivity for its reuse of 5 times.
