间苯二酚催化加氢制备1,3-环己二醇的研究

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。

Study of the Synthesis of 1,3-Cyclohexanediol Through Catalytic Hydrogenation of Resorcinol

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.
