以SDB为载体的疏水催化剂在化学工业中的研究进展

Advance in the application of hydrophobic catalyst over SDB in chemical industry

摘要:

在反应物、反应介质或产物中有水的一些催化反应过程中，水对亲水性催化剂的活性及寿命影响很大。疏水性催化剂可以克服由于水对活性组分覆盖而使催化剂的活性减弱及寿命降低等不足。SDB（苯乙烯-二乙烯基苯共聚物）以其独特的疏水性能，近年来在疏水催化剂制备方面愈来愈得到广泛的关注。本文综述了近年来以SDB为载体的疏水催化剂在核化工及合成饱和酸/酯、烯酸/酯等化学品方面的研究进展，展望了其良好的应用前景。

Abstract:

In water-containing catalytic reactions, regarding of whether water is reagent, reaction medium or product, water has much influence on the activity and life of hydrophilic catalysts. Hydrophobic catalysts can well overcome the disadvantage of hydrophilic catalysts by avoiding the coverage of water on active components. In recent years, SDB (styrene-divinylbenzene copolymers) have got more and more attention in the field of catalyst preparation due to the distinct hydrophobicity of SDB. Advances of research and application of hydrophobic catalysts over SDB in nuclear industry and the production of saturated acid /ester and olefine acid /ester were reviewed in this paper. Based on the research, the room of research and application of the hydrophobic catalyst was prospected.
