摘要
研究了温和条件下钯催化剂催化六氯苯加氢脱氢反应． 结果表明， Ｐｄ Ｃｌ２ 催化活性不高，而 Ｐ Ｖ Ｐ 负载 Ｐｄ Ｃｌ２ 活性较高． Ｐ Ｖ Ｐ 负载 Ｐｄ Ｃｏ 催化剂具有双金属协同效应，提高了催化活性．５５ ℃下，该催化剂在 Ｃｏ／ Ｐｄ 摩尔比为０５ 时表现出最高的催化活性．
Palladium catalysts used in the hydrodechlorination of perchlorobenzene under mild conditions were investigated. The results showed that PdCl 2 was not so active for the hydrodechlorination of perchlorobenzene while polyvinyl pyrrolidone (PVP) supported PdCl 2 showed high activity. PVP supported Pd Co catalyst displayed a synergic effect and its catalytic activity raised further. This catalyst exhibited the highest activity at a Co/Pd molar ratio of 0 5 and 55℃.
