甲醇羰基化制乙酸反应催化剂的分子设计
Molecular Designing of the Catalyst for Carbonylation of Methanol to Acetic Acid
摘要
Abstract
Pyridine carbonylic acid Rh catalyst ( [ MRh( CO) 2 ] +, M:pyridine carbonylic acid complexes ) and its homolog, isomer were studied by using the ab initio method with the effective core potential ( ECP) approximation in HF/LANL2DZ level.From the view of topological analysis of the electronic density , electronic density and Laplacian of all catalysts’ critical points were studied.The results indicated that the center metal (Rh) of [MRh(CO)2] +catalyst and its homolog and isomer haven ’ t more effective charge when they employed asymmetric chelate ligand .The o-acetic acid-pyridine-Rh catalyst has the lowest reaction energy barrier and the weakest Rh-O covalence orbitals interreaction which tends to break .关键词
