摘要： 近十多年来,均相络合催化剂的固载化是一个活跃的研究领域[1-6],我们在聚合、歧化、加氢等络合催化剂负载化方面的工作[7-9]。说明负载型络合催化剂中的载体,可以视为一个配体,由于其有不同的化学及空间效应,因此是一个复杂的配体.在环戊二烯选择加氢的研究中,不同载体对加氢反应的活性及选择性的影响,说明载体的性质、结构、分子量及其上基团,对于底物的配位和它在活性物种上的加氢速度常数都有调变作用[10],本文报道固载化络合催化剂在多种不饱和烃加氢反应中的行为.

Abstract: The behaviors of three supported coordination catalysts,PdCl2-Tussah silk,PdCl2PVP(polyvinylpyrrolidone),PdCl2-PVP/Al2O3 in the hydrogenation of 1-hexene,1decone,2-ethyl-hexene,crotonaldehyde,cinnamaldehyde and cyclododecatriene were investigated,the activities of these substrates were different from catalyst to catalyst.The hydrogenation rates of the substrates with large space hindranceover PdCl2-PVP catalyst were higher than that over PdCl2-Tussah silk catalyst.The larger the space hindrance disparity,the more the difference between the activities of these two catalysts.Most of the substrates show higher activities in reaction over PdCl2-PVP/Al2O3.The hydrogenation selectivities were also different for different catalysts.

Key words: Supported catalyst, Palladium catalyst, Hydrogenation catalyst
