以天然生物高分子羊毛为载体制备了羊毛-钯络合物催化剂。用XPS、IR方法对羊毛-钯络合物进行了初步表征。证明羊毛-钯络合物在常温常压下能够催化各种化合物,如硝基苯、苯甲醛、丙烯醇、丁烯睛、醋酸乙烯酯、苯乙烯和1-己烯的加氢,分别以大约100%的收率得到了苯胺、苯甲醇、正丙醇、丙胺、醋酸乙酯,乙苯和己烷。对于用以往的催化剂较难加氢的各种脂肪醛,如丙醛、丁醛、戊醛和己醛,在常温常压下也能够进行催化加氢,分别以大约100%的收率得到正丙醇、正丁醇、正戊醇和正己醇。这种催化剂稳定性也很高,长时间反应也能保持高活性,钯不脱落。
Wool - palladium complex catalysts were prepared from natural biopolymer wool. Wool - palladium complexes were characterized by XPS and IR methods. It is proved that the wool-palladium complex can catalyze the hydrogenation of various compounds such as nitrobenzene, benzaldehyde, allyl alcohol, butylene eye, vinyl acetate, styrene and 1-hexene at normal temperature and pressure, Aniline, benzyl alcohol, n-propanol, propylamine, ethyl acetate, ethylbenzene and hexane were obtained in about 100% yield. Various aliphatic aldehydes, such as propionaldehyde, butyraldehyde, pentanal and hexanal, which are more difficult to hydrogenate with conventional catalysts, can also be catalytically hydrogenated at room temperature and normal pressure to give n-propane at about 100% yield Alcohols, n-butanol, n-pentanol and n-hexanol. This catalyst is also very stable, long-term reaction can maintain high activity, palladium does not fall off.
