Abstract

An algorithm is developed for calculating the dissociation constants of weak organic acids in isopropyl alcohol. The procedure is based on spectrophotometric data in the UV and visible regions without measuring the pH of the medium or using buffer solutions. A new way of determining analytical wavelengths in spectrophotometry is proposed. The original algorithm is tested experimentally for seven organic acids of different strengths, and the relative error in determining the dissociation constants does not exceed 1%.

计算异丙醇中有机酸的质子分解平衡常数的算法

摘要

开发了一种计算弱有机酸在异丙醇中的解离常数的算法。该程序基于紫外和可见光区域的分光光度数据，无需测量介质的 pH 值或使用缓冲溶液。提出了一种在分光光度法中确定分析波长的新方法。原始算法对七种不同强度的有机酸进行了实验测试，确定解离常数的相对误差不超过 1%。
