性质:又称催化加氢,一般是指烯烃、炔烃或双烯烃等不饱和烃在催化剂作用下加氢形成饱和烃的过程。饱和烃化合物也可催化加氢,它在催化剂作用下某些键断裂,同时加氢。有均相与多相催化加氢。均相催化加氢一般使用威尔金森型催化剂RhCl(PPh3)3;多相催化加氢多使用过渡金属及它们的氧化物和硫化物。此外,加氢分解、CO加氢还原合成甲醇,羰基合成以及—NO2,—CN、  C=O  —COOR,—COOH的加氢还原也属于催化氢化。催化剂有铂、钯、雷尼镍、亚铬酸铜等。铂钯催化剂活性高、用量少、反应条件温和;雷尼镍应用最广泛;亚铬酸铜成本低,对醛、酮、酯、酰胺、酰亚胺等含有羰基的化合物有较高的催化活性。近年来新发展的铑、钉、铱等带有各种配位基的均相催化剂,活性高,选择性好,反应条件温和,在常温、常压下就能反应。催化氢化在工业上有广泛的用途。例如:在油脂工业中,可将液态油催化加氢为固态脂肪,生产肥皂和硬化油。
