用二苯基氯化膦对三乙烯四胺乙基膦酸 磷酸氢锆载体Zr(HPO4 ) 2 -2x[O3 PCH2 CH2 (NHCH2 CH2 ) 3 NH2 ]x·H2 O(简称ZP TETAEPA)表面进行二苯基膦化 ,制得了二苯基膦化的载体ZP TETAEPA DPP和相应的负载络合钯催化剂ZP TETAEPA DPP Pd ,用IR ,TG ,DTA及元素分析对它们进行了表征 ,着重研究了x值所反映的活性基团在载体表面的空间分布对ZP TETAEPA DPP Pd催化剂羰化反应催化活性的影响 ,并讨论了这种影响因素在其它混合磷酸锆类催化剂中存在的普遍性 .
The surface of Zr (HPO4) 2-xx [O3 PCH2 CH2 (NHCH2 CH2) 3 NH2] x · H2 O (ZP TETAEPA) Phenylphosphine to give the diphenylphosphine carrier ZP TETAEPA DPP and the corresponding supported palladium complex catalyst ZP TETAEPA DPP Pd, which were characterized by IR, TG, DTA and elemental analysis, focusing on the value of x The influence of the spatial distribution of the active groups on the surface of supported ZP TETAEPA DPP Pd catalysts was discussed. The effects of these factors on the other zirconium phosphate catalysts were also discussed.
