以RhCl3·3H2O和1,5-环辛二烯为原料制备了[Rh（COD）Cl]2催化剂，并利用傅里叶变换红外光谱仪（FTIR）和X射线光电子能谱（XPS）对其进行了表征。以α-蒎烯加氢为探针反应，考察了COD/Rh摩尔比、回流温度及回流时间对催化剂催化性能的影响，并通过正交试验确定了催化剂适宜的制备条件：COD/Rh摩尔比（1,5-环辛二烯与三水合氯化铑摩尔比）3.5：1，回流温度75℃，回流时间3.5h。将该条件下制备的[Rh（COD）Cl]2催化剂用于α-蒎烯加氢反应，α-蒎烯转化率达97.3%以上，顺式蒎烷对映选择性高于97.5%，顺式蒎烷收率达95.0%以上。与文献报道的其他工艺相比，该工艺特点是加氢条件比较温和，选择性高，催化效率高，能耗低。%Rh(COD)Cl]2catalyst was prepared by using RhCl3·3H2O and 1,5-cyclooctadiene as raw materials and characterized by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Takingα-pinene hydrogenation as a probe reaction,we investigated the effects of COD/Rh molar ratio,reflux temperature and reflux time on the catalytic properties. The suitable conditions for preparing the catalysts were proposed through orthogonal experiment,which were COD/Rh molar ratio of 3.5∶1,reflux temperature of 75℃ and reflux time of 3.5h. Then the conversion ofα-pinene was above 97.3%,the enantioselective of cis-pinane was above 97.5% and the yield ofcis-pinane was above 95.0%. Compared with other processes reported in the literature,the proposed process had features of mild hydrogenation conditions,high enantioselective,high catalytic efficiency and low energy consumption.
