高熔点熔融有机盐N-烷基吡啶鎓六氟磷酸盐已被用作温控载体。研究了熔融有机盐的结构对硅氢加成反应的影响，发现吡啶上的烷基链对催化活性和选择性有影响。此外，采用这种调温催化剂载体，在反应条件下催化剂相为液相，而在室温下以熔融有机盐为载体的催化剂为固相，可以简单地通过倾析重复使用。(C)2008 Elsevier B. V.保留所有权利。
The high melting point molten organic salts N-alkylpyridinium hexafluorophosphates have been used as thermoregulated supports. The influence of the structure of the molten organic salts on hydrosilylation reactions has been investigated and it was found that the alkyl chains attached to the pyridinium have an impact on the catalytic activities and selectivities. Additionally, by using this kind of thermoregulated catalyst support, the catalyst phase is liquid phase under the reaction conditions, whereas the catalyst supported by molten organic salt is solid phase at room temperature, therefore, it can be reused simply by decantation.
