针对目前工业生产中正丁醛自缩合合成辛烯醛使用液体碱催化剂所带来的环境污染严重、生产成本高、产物选择性低等缺点,着重分析了研究开发中的各种固体碱催化剂的优缺点,并指出了提高催化稳定性是其研究方向。此外,还对酸碱双功能固体作为该反应催化剂进行了展望。 In view of the serious environmental pollution, high production cost and low product selectivity brought by the use of liquid base catalyst for the self-condensation of n-butyraldehyde to synthesize octenal in industrial production, the advantages of various solid base catalysts in research and development are analyzed emphatically Shortcomings, and pointed out that to improve the catalytic stability is its research direction. In addition, the prospects of using acid-base bifunctional solid as the reaction catalyst were also discussed.
