摘要

本文报导了二步串联-平行反应速度常数(k_2/k_1

k_1)计算公式的新推导方法和步骤.在k_2/k_1等于17个特征值和反应物的初始浓度比处于上、下界限之间的条件下

导出了一组精确k_1算式

在其他条件下则可导得近似k_1算式.所有k_1算式被归纳成一个综合通式.本算法还被推广于推导三步和多步串联-平行反应速度常数的算式.在聚砜磺化反应动力学的研究中

应用本算法得到了满意的结果.

Abstract

Is this article

a new mathematical procedure for calculating the rate constants(k2/k1

k1)in 2-step series-parallel second-order reactions is presented. Under specific conditions

when k2/k1 is equal to one of 17 specific values and initial molar ratio of the reactants lies between the lower and upper boundary values

a set of exact equations for the determination of k1 are derived

in other cases

approximate equations or approximation method are proposed. All the exact and approximate equations can be covered by a equation. This procedure can be extended to derive multi-step series-parallel reactions. Finally this procedure is applied to the kinetic study of sulfonation of polysulfone and satisfactory results are obtained.
