聚苯乙烯(PS)是匀相催化剂多相化研究中常用的高分子载体,但通常涉及的均是交联聚苯乙烯(CPS)。本文制备了不同链长的直链聚苯乙烯(LPS)负载钯催化剂(LPSN-Pd);将其与相应的交联聚苯乙烯负载的钯催化剂(CPSN-Pd)对比,考察了这类催化剂对不饱和烃类加氢反应的活性、选择性以及起始载体链长对催化刑加氢性能的影响。
Polystyrene (PS) is a commonly used polymeric carrier used in the heterogeneous phase change studies of homogeneous catalysts, but cross-linked polystyrenes (CPSs) are commonly involved. In this paper, LPSN-Pd (LPSN-Pd) with different chain length was prepared. Compared with the corresponding crosslinked polystyrene supported palladium catalyst (CPSN-Pd), this kind of catalyst Hydrogenation reaction of unsaturated hydrocarbons, selectivity and initial chain length of the catalyst on the catalytic performance of the hydrogen.
