摘要
通过间苯二酚的多相催化加氢制备得1,3-环己二醇,探讨了不同反应条件:溶剂、催化剂、反应温度和反应时间等对间苯二酚转化率及1,3-环己二醇收率的影响.反应结果表明:稳定镍的催化加氢作用明显强于超细还原铁粉和钯;催化加氢反应在非极性溶剂中几乎不反应,而在乙醇反应体系反应良好;由于1,3-环己二醇能进一步被转变为环己醇等副产物故反应时间不宜过长,反应温度,不宜过高.
1,3-Cyclohexanediol was prepared through multiphase-catalytic hydrogenation of resorcinol. The influences of solvent, catalyst, reaction-temperature and reaction-time on the yield of 1, 3-cyclohexanediol and the conversion of resorcinol are studied. The result show that the function of catalytic hydrogenation of stable nickel is remarkably better than that of reductive-iron powder and palladium; the catalytic hydrogenation reaction goes on well in the polarity solvent , while it almost dose not take place in the non-polarity solvent; and the reaction -temperature should not be too high and the time should not be too long because 1, 3-cyclohexanediol can be further converted into some byproducts such as cyclohexanol, the reaction -temperature should not be too high and the time should not be too long.
