摘要

在温度为298.15、303.15、308.15和313.15 K时,测定了尼美舒利在0.1、0.2、0.4、0.6、0.8、1和2 mol dm-3的亲水剂(苯甲酸钠、水杨酸钠、溴化钠和烟酰胺)水溶液中的电导值。利用谢德洛夫斯基外推法,用电导值来计算极限摩尔电导和缔合常数。计算了尼美舒利在亲水剂水溶液中缔合过程的热力学参数。

Conductometric Study of Nimesulide in Aqueous Solutions of Hydrotropic Agents at Different Temperatures
Conductance values of nimesulide have been determined in water in 0.1, 0.2, 0.4, 0.6, 0.8, 1 and 2 mol dm-3 aqueous solutions of hydrotropic agents (sodium benzoate, sodium salicylate, sodium bromide and nicotinamide) at temperatures 298.15, 303.15, 308.15 and 313.15 K. The conductance values have been used to evaluate the limiting molar conductance and association constants by means of Shedlovsky extrapolation technique. Thermodynamic parameters for the association process of nimesulide in aqueous solutions of hydrotropic agents have also been calculated.
