A polymer-palladium complex prepared from palladium (Ⅱ) chloride and poly-γ-aminopropylsiloxane suported on fumed silica is very active for hydrogenation of olefins in proper solvents at 30℃ tinder an atmospheric hydrogen pressure. The rates of hydrogenation of olefins by the polymer complex are found to be markedly affected by the palladium content in the polymer complex.

It was found that the activities of these complexes are higher than those of their low molecular analogues, and have a clear relation to the polymer bound N/Pd molar ratio, resin particle size, and swelling and coordination ability of the solvents. For hydrogenation of alkene, these polymer complexes are possessed of good selectivity...

The complexes of polyvinylpyridine-palladium chloride have been synthesized and characterized, and their catalytic properties for hydrogenation of olefins have been investigated. It was found that the activities of these complexes are higher than those of their low molecular analogues, and have a clear relation to the polymer bound N/Pd molar ratio, resin particle size, and swelling and coordination ability of the solvents. For hydrogenation of alkene, these polymer complexes are possessed of good selectivity which varies also with the polymer bound N/Pd molar ratio.These polymer complexes are stable in air and can be used repeatly without appreciable loss in activity, and no detectable palladium found in solution. Their stability against the reduction by hydrogen is also better than that of their low molecular analogues.

This catalyst displayed a high activity for hydrogenation of olefins in proper solvents under an atmospheric pressure of hydrogen at 20-40℃, for example, 20 mM styrene was hydrogenated completely with about 40 mg catalyst containing 0.0033 mg atom of Pd in isopropanol within 1 hour. It also exhibited good selectivity. Styrene,α-methylstyrene, acrylonitrile, acrylic acid and its ester could be smoothly...

A poly-γ-(m-diphenylphosphinophenyl)propylsiloxane-Pd complex catalyst supported on fumed silica is described. This catalyst displayed a high activity for hydrogenation of olefins in proper solvents under an atmospheric pressure of hydrogen at 20-40℃, for example, 20 mM styrene was hydrogenated completely with about 40 mg catalyst containing 0.0033 mg atom of Pd in isopropanol within 1 hour. It also exhibited good selectivity. Styrene,α-methylstyrene, acrylonitrile, acrylic acid and its ester could be smoothly hydrogenated.Cyclopentadiene, isoprete.e ard α-pinene could rot be hydrogenated under the same conditions. Thus, this polymer catalyst is especially suited to the hydrogenation of the ethylenic double bonds which are linked to aromatic, cyano, carboxyl and ester groups. Furthermore, it could be reused for sveral times without a serious loss of activity.

以烟雾状二氧化硅为载体的聚-γ-(m-二苯膦苯基)丙基硅氧烷和氯亚钯酸钠四水合物作用制备的高分子钯络合物,在溶剂中和一个氢压下具有很高的烯烃加氢活性。例如,20毫克分子的苯乙烯在含有0.0033毫克原子钯的这种催化剂存在下,于40℃一小时内完全氢化。它的选择性也是很明显的。尽管苯乙烯、α-甲基苯乙烯、丙烯腈、丙烯酸及其酯在几小时内可以完全氢化,但环戊二烯、异戊二烯、α-蒎烯在同样条件下却完全不能氢化。苯基、氰基、酯基、羧基在反应中不受影响。因此,这一聚合物催化剂特别适用于和芳基、腈基、羧基和酯基相连的双键的氢化。此外,催化剂能再次使用,催化活性降低不严重。
