摘要:

以聚(4-乙烯吡啶)(PVP)与乙酸、盐酸、聚丙烯酸的分子复合物为载体,制备了均相的高分子负载钯催化剂(简称PVP/HAc-Pd,PVP/HCl-Pd,PVP/PAA-Pd),研究了这些催化剂对于硝基苯氢化反应的活性,发现PVP/HAc-Pd的活性及稳定性为最好,且比以聚(4-乙烯吡啶)为载体的负载钯催化剂有显著提高,无机强碱KOH的存在对反应有明显的加速效应.详细讨论了各种碱、KOH用量、溶剂以及温度对PVP/HAc-Pd催化硝基苯加氢性能的影响.结果表明:PVP/HAc-Pd中,4-乙烯吡啶与乙酸的最

Abstract:

Homogeneous polymer-supported palladium catalysts (referred to as PVP/HAc-pd, pvp/hc-pd, pvp/paa-pd) were prepared using the molecular complex of poly(4-vinylpyridine) (PVP) and acetic acid, hydrochloric acid and polyacrylic acid as the carrier, and the activity of these catalysts for nitrobenzene hydrogenation was studied, and it was found that the activity and stability of PVP/HAc-Pd were the best, and it was significantly improved than that of poly(4-vinylpyridine) supported palladium catalysts. The presence of inorganic strong base KOH has a significant acceleration effect on the reaction. The effects of various alkalis, KOH dosage, solvent and temperature on the hydrogenation performance of nitrobenzene catalyzed by PVP/HAc-Pd were discussed in detail. The results showed that among PVP/HAc-Pd, 4-vinylpyridine and acetic acid were the most
