【摘要】 <正> 齐格勒（Ziegler）型均相加氢催化剂在加氢反应中的应用目前还处于开发阶段,但已引起人们的重视。我们对M（acac）_Et₃Al-Py（M=Fe（III）、Co（III）、Co（II）、Ni（II）,n=2～3,Py为吡啶）催化体系在用环戊二烯（CPD）选择性加氢制取环戊烯（CPE）中的应用进行了研究,但所用催化剂的母体M（acac）_更多还原

【Abstract】 Synthetic methods o group VIII metal acetylacetonates of Fe(III),Co(III),Co(II),Ni(II)and the factors affecting them are given in this paper.Their dissolution behaviour in usual solvents and solubility curves in toluene have been studied.This work provides the parent catalysts for selective hydrogenation of M(acac)_-Et_Al-Pyridine(M=Fe(III),Co(III),Co(II),Ni(II);n=2～3)and provides the basic data for selecting solvents.Such catalyst systems for the hydrogenation of cyclopentadiene to cyclopentene give excellent results.更多还原
