对钴膦催化剂丙烯低压制丁醇反应机理的探析

Investigation of the Mechanism for Hydroformylation of Propene to Butanol with Complex Co-P Catalyst

文献[1]假定每一个总包反应均为一级基元反应,提出了钴膦催化剂丙烯低压醛化制丁醇的五种可能反应机理,并通过速度常数计算认为反应只能按其中一种机理进行。本文通过热力学平衡常数计算和动力学理论对该反应作进一步研究。认为文献[1]中的研究方法和结论均存在一定的问题。

It is supposed in the reference [1] that each reaction is first order elementary reaction. Five possible reaction mechanisms for hydrofor-mytation of propene to butanol under low pressure with Co-P catalyst are suggested. And considered through the calculations of rate constant that the reaction can only be carried out according to one of the mechanisms. In this paper, the mechanism is further studied with the calculations of thermodynamic eqilibrium constant and the theory of kineties. It is considered that the supposition is untenable in the reference [1], problems to a certain degree are presented in the development method and the conctusion.
