摘　　要：正戊醛自缩合合成2-丙基-2-庚烯醛反应是工业生产2-丙基庚醇的重要步骤之一,针对该反应中液体碱催化剂所带来的生产成本高、产物选择性低、环境污染严重等缺点,着重分析了固体碱催化剂和固体酸催化剂的研究状况,指出了提高固体碱催化稳定性以及固体酸催化活性和选择性是今后的努力方向。并对开发具有高催化性能的酸碱双功能固体催化剂进行了展望。The synthesis of 2-propyl-2-heptenal via valeraldehyde self-condensation is one of the important chemical processes for industrial manufacture of 2-propylheptanol.There are some drawbacks in the present industrial process using liquid alkali catalyst,such as high production cost,low desired product selectivity,serious environmental pollution,and so on.Therefore,emphases were put on the analyses of the researches on solid base and solid acid catalysts.On the basis of the analyses,it is pointed out that the improvement of the catalytic stability of solid base catalysts and of the catalytic activity and selectivity of solid acid catalysts will be the further research direction.Development of acid-base bifunctionalized solid catalysts with high catalytic performance will be expected in the future.
