摘要
采用可溶性有机高分子负载钯络合物作催化剂 ,在无机碱 (NaOH)存在下于 2 0～ 65℃的有机溶液中进行常压加氢脱卤反应。研究了脱卤反应的温度、溶剂量、碱量、压力对反应的影响。结果表明 :负载钯络合催化剂催化效率高、反应体系简单、无副反应 ,是一种很好的卤代苯加氢脱卤方法 。
Benzene halide was hydrogenated and dehalogenated under ordinary pressure with inorganic base at 20～65℃, by using a resolvable organic polymer supported palladium complex as catalyst.The infleuences of the temperature,solvent,quantity of dispersants,alkali for dehalogenation and pressure on the reaction were investigated.The results showed that the catalytic efficiency of the supported palladium complex is high,the reactive system in simple and there is no side reaction. It is an effective method of hydrogenation and dehalogenation for halogenated hydrocarbon compounds and can be used widely in organic chemical industry and for environmental protection.
