The solubility of dipyridamole p-toluene sulfonate in seven monosolvents (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, isobutanol, 2-butanol) and three different binary solvents (methanol + ethanol, methanol + 1-propanol, methanol + 1-butanol) was measured by a gravimetric method at temperatures ranging from 288.15 to 328.15 K. The experimental results indicate that the solubility of dipyridamole p-toluene sulfonate increases with increasing temperature while showing negative correlation with the mole fraction of organic solvents (ethanol, 1-propanol, 1-butanol) at a given temperature in binary solvents. The Apelblat model, the CNIBS/R-K model, and the modified version of Jouyban-Acree models (the Apel-JA equation) were used to correlate the experimental data, and the calculated results of above models were found to agree well with the experimental data.

双嘧达莫对甲苯磺酸盐在7种醇溶剂和3种二元溶剂中的溶解度测定及相关性

双嘧达莫对甲苯磺酸盐在七种单溶剂（甲醇，乙醇，1-丙醇，2-丙醇，1-丁醇，异丁醇，2-丁醇）和三种不同的二元溶剂（甲醇+乙醇，甲醇+ 1-丙醇，甲醇+ 1-丁醇）的重量法在288.15至328.15 K范围内进行了测量。实验结果表明，双嘧达莫对甲苯磺酸盐的溶解度随温度的升高而增加，但与有机溶剂的摩尔分数呈负相关关系（乙醇，1-丙醇，1-丁醇）在给定温度下的二元溶剂中。使用Apelblat模型，CNIBS / RK模型和Jouyban-Acree模型的修改版本（Apel-JA方程）来关联实验数据，
