- 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
