本文以便宜的高分子做载体原料,制备了三种新的聚合氧膦——钯络合催化剂。在烯烃及硝基苯的催化氢化中,其活性明显优于文献中二价钯类型的催化剂。1 实验1.1 药品及仪器微晶纤维素(层析用)直链淀粉(自制),聚乙烯醇为试剂级,二水合氯化钯为分析纯,氯化二苯基膦(自制)。103—型气相色谱仪;ESCALABMKⅡ光电子能谱仪;P—E—3030原子吸收分光光度计:ALPHA CENTAVRI 红外光谱仪,721A 型分光光度计。
In this paper, three new polyphosphorus oxide-palladium complex catalysts were prepared by using cheap polymers as carrier materials. In the catalytic hydrogenation of olefins and nitrobenzenes, the activity is significantly better than that of the divalent palladium-type catalysts in the literature. 1 Experimental 1.1 Drugs and equipment Microcrystalline cellulose (chromatography) amylose (homemade), polyvinyl alcohol as reagent grade, palladium chloride dihydrate analytical grade, diphenylphosphine chloride (homemade). 103-type gas chromatography; ESCALABMK Ⅱ photoelectron spectrometer; P-E-3030 atomic absorption spectrophotometer: ALPHA CENTAVRI infrared spectrometer, 721A spectrophotometer.
