本工作以强碱性阴离子交换树脂作载体制备了相应的高分子钯络合物催化剂,检验了其对棉籽油加氢的活性和选择性,考查了不同制备条件对催化剂活性的影响,求出其催化加氢的表现动力学方程为:r=KPH_2 近年来,高分子固载金属络合物催化剂以其优异的性能,引起了人们广泛的重视,做了大量的研究工作。但大部分着眼于共价键联高分子催化剂的研究,而对离子键合形式研究较少。离子交换树脂合成方便,原料易得,机械强度好且为球状颗粒易于回收再用,是一种理想的高分子催化剂载体,制备了高分子—钯络合物催化剂,考察了所得催化剂对棉籽油的催化加氢性能及其表观动力学行为。
In this work, a strong base anion exchange resin was used as a carrier to prepare the corresponding polymer palladium complex catalyst. The activity and selectivity of hydrogenation to cottonseed oil were tested. The effects of different preparation conditions on the catalyst activity were investigated. Its catalytic hydrogenation performance kinetic equation: r = KPH_2 In recent years, polymer-supported metal complex catalysts for its excellent performance, has attracted widespread attention, done a lot of research work. However, most of them focus on the study of covalently linked polymer catalysts, but few studies on the ionic bonding form. The synthesis of ion exchange resin is convenient, the raw materials are easy to obtain, the mechanical strength is good and the spherical particles are easy to be reused, which is an ideal polymeric catalyst carrier, preparing a polymer-palladium complex catalyst. The effects of the obtained catalyst on cottonseed oil Catalytic hydrogenation performance and its apparent kinetic behavior.
