| 摘 要： | 在气相体系中考察了固载于活性炭 (C)上的磷钨 (PW12 )、硅钨 (SiW12 )及磷钼 (PMo12 )杂多酸对异丙醇脱水反应的催化性能 .不加水时主要生成丙烯 ;加入适量的水有助于降低丙烯而提高异丙醚的选择性 ;催化活性除与酸性有关外 ,与杂多酸的特殊结构“假液相”模型密切相关

| Abstract: | The catalytic characteristics of heteropoly acid(HPA) with Keggin structure,supported on activated carbon,was investigated for dehydration of isopropyl alcohol in vapor phase.The experiment showed that the right amount of water added into the system could improve the selectivity of diisopropyl ether while the amount of propene in products decreased.The catalytic activity was related to both acidfity and HPA, pseudo_liquid phase model. |

| Keywords: | supported heteropoly acids isopropyl alcohol diisopropyl ether |
