In this work, the solubility of forchlorfenuron [N-(2-chloro-4-pyridinyl)-N′-phenylurea (CPPU)] in 12 selected pure solvents (n-pentanol, n-butanol, n-propanol, ethanol, methanol, ethyl acetate, n-propyl acetate, n-butyl acetate, i-propyl acetate, i-butyl acetate, i-amyl acetate, and acetone) was determined under the conditions of 0.1 MPa and 278.15–323.15 K using the laser detection method. The results indicate that the solubility of CPPU in the selected solvents is proportional to temperature. Five models (Two-Suffix Margules, NRTL, λh, Universal Quasi-Chemical, and the modified Apelblat) were selected to fit the solubility data of CPPU in pure solvents. By comparison, it is found that the modified Apelblat model has a better fitting effect. The solubility rules of CPPU in different solvents were analyzed using Hansen solubility parameters and polarity. The solvent effect of CPPU solubility in different solvents studied was discussed using the KAT-LSER model. The above studies can supply some primary data for the crystallization process of CPPU.

氟虫脲在12种有机纯溶剂中不同温度下的溶解度测定及汉森溶解度参数

在这项工作中,氯苯脲 [ N -(2-chloro-4-pyridinyl) -N '-phenylurea (CPPU)] 在 12 种选定的纯溶剂(戊醇、丁醇、正丙醇、乙醇、甲醇)中的溶解度, 乙酸乙酯, 乙酸丙酯, 乙酸丁酯, 乙酸丙酯, 乙酸丁酯, i在 0.1 MPa 和 278.15–323.15 K 的条件下,使用激光检测法测定了乙酸戊酯和丙酮)。结果表明,CPPU 在所选溶剂中的溶解度与温度成正比。选择了五种模型(Two-Suffix Margules、NRTL、λh、Universal Quasi-Chemical 和改进的 Apelblat)来拟合 CPPU 在纯溶剂中的溶解度数据。对比发现,修正后的Apelblat模型拟合效果更好。利用汉森溶解度参数和极性分析了CPPU在不同溶剂中的溶解规律。使用 KAT-LSER 模型讨论了 CPPU 在所研究的不同溶剂中溶解度的溶剂效应。以上研究可为CPPU的结晶过程提供一些初步数据。
