摘要

采用紫外光谱法研究了间硝基苯甲酸与硝酸在不同浓度硫酸介质中的硝化反应动力学。所观察到的间硝基苯甲酸硝化速率与烷基苯硝化速率的差异与羧基的吸电子性质及其质子化有关。在反应过程中，不仅生成了3,5-二硝基苯甲酸，而且生成了摩尔吸收系数显著提高的产物

KINETICS OF NITRATION OF M-NITROBENZOIC ACID IN AQUEOUS SOLUTIONS OF SULFURIC ACID

The kinetics of the nitration reaction of m-nitrobenzoic acid with nitric acid in a sulfuric acid medium of various concentrations was studied by UV spectroscopy. The observed differences in the rate of nitration of m-nitrobenzoic acid from the nitration of alkylbenzenes are associated with the electron-withdrawing nature of the carboxyl group, as well as with its protonation. During the reaction, not only 3,5-dinitrobenzoic acid is formed, but also products with significantly higher molar absorption coefficients
