By using Cs H salt of heteropolyacid as catalysts, hydration of olefins, N-alkylation of acrylonitrile with alcohol as a highly difficult reaction, and solid-state Beckmann rearrangement have been investigated. In hydration of cyclohexene, H-ZSM-5 was much more active. However, for the more bulky olefins, the heteropoly compound was superior in activity to H-ZSM-5. In addition, N-alkylation of acrylonitrile with isopropyl alcohol, the heteropoly compound exhibited a catalytic activity, while the yield was still low. Furthermore, the heteropoly compound was efficient for solid-solid rearrangement of Beckmann rearrangement of cyclododecanone oxime. It was found that Cs2.1 salt exhibited a sharp shape selectivity for hydrogenation and oxidation. These results demonstrated that the heteropoly compounds are promising solid acids for clean chemical processes.

以Cs-H杂多酸盐为催化剂，研究了烯烃水合反应、丙烯腈与醇的N-烷基化反应和固相Beckmann重排反应。在环己烯水合反应中，H-ZSM-5的活性要高得多。然而，对于体积较大的烯烃，杂多化合物的活性优于H-ZSM-5。此外，杂多化合物丙烯腈与异丙醇的N-烷基化反应表现出一定的催化活性，但产率仍然较低。此外，杂多化合物对环十二酮肟的Beckmann重排反应具有较高的固固重排活性。结果表明，Cs2.1盐对氢化和氧化具有很强的择形选择性。这些结果表明，杂多化合物是一种很有前途的清洁化学过程的固体酸。
