摘　　要：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。The catalysts for the synthesis of 2-ethyl-2-hexenal via n-butyraldehyde self-condensation were reviewed. There are several disadvantages such as serious environmental pollution, high production cost and low desired product selectivity in industrial technology using liquid alkali catalyst. Based on the analysis for the advantages and disadvantages of solid bases catalysts in R＆D it is pointed out that the improvement of their catalytic stability will be the further research direction. Additionally acid-base bifunctionalized solid will be expected as the catalyst for n-butyraldehyde self-condensation in the future.
