贵刊14(4),1986发表了《动力学方法测定络合比》一文。提出了测定络合比的动力学方法,认为:对一个络合物MR_n,其动力学方程可表示为: d〔MRn〕/dt=k〔M〕〔R〕~n用动力学方法测出n,即可知该络合物的络合比为1:n,并断定该法简便,结果可靠,只要反应速率能够控制在适当范围内,都可用此法测定络合比。我们认为:用动力学法测定络合比方法中的有些问题还值得商榷。在与作者的商榷信件中,作者提出了他如下的反应机理: Your publication 14 (4), 1986 published a “kinetic method to determine the ratio of complex” article. The kinetic method for determining the complex ratio is proposed. The kinetic equation for a complex MR_n can be expressed as: d [MRn] / dt = k [M] [R] ~ n n, we can see that the complex complex ratio of 1: n, and concluded that the method is simple and reliable results, as long as the reaction rate can be controlled within the appropriate range, can be used to determine the complex ratio. We think: kinetic method to determine the complexation ratio of some of the issues is also debatable. In a deliberate letter with the author, the author proposed his reaction mechanism as follows:
