| Research Abstract |
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.
