摘要
以负载型铜、镍催化剂为加氢催化剂 ,液相加氢还原粗仲辛醇中的 2 辛酮制备高纯度仲辛醇。分析了催化剂的制备方法、类型及加氢反应条件对催化剂活性的影响。实验结果表明 ,镍催化剂的加氢活性较高 ,加氢反应条件相对缓和。在适当的加氢条件下 ,采用浸渍法制备的镍催化剂和采用共沉淀法制备的铜催化剂的加氢活性相当 ,2 辛酮的加氢转化率均可达 98%以上 ,加氢产物中仲辛醇的纯度达 98%～ 99% ,2 辛酮含量可降至 0 .2 %以下。负载型镍、铜催化剂具有良好的活性稳定性 ,是制备高纯度仲辛醇的高效、高选择性催化剂 ,具备一定的工业开发潜力。
The supported copper and nickel catalysts are applied to preparation of purified octanol 2 by using hydrogenation reduction. The effects of catalyst preparation method and operating conditions for the hydrogenation activity of catalysts were tested. The catalysts were prepared by impregnating or coprecipitation method by adding basic oxides and transitional metal oxides as promoters. The experimental results revealed that the nickel catalyst prepared by impregnating method and copper catalyst prepared by coprecipitation method displayed a similar catalytic activity under the suitable conditions. The octanone 2 conversion rates of both catalysts are all over 98%, and the purity of octanol 2 can get to 98%～99%, while the content of octanone 2 in products may be lowered below 0.2%. The reaction conditions of nickel catalyst are relatively mild due to the relatively high catalytic activity of catalysts.
