采用重量法测定了格列齐特在甲醇、乙醇、正丙醇、异丙醇、正丁醇、异丁醇、仲丁醇、丙酮、环己酮、甲酸乙酯、乙酸甲酯、乙酸乙酯、乙腈、四氢呋喃、N,N-二甲基甲酰胺、氯仿和甲苯等17种纯溶剂中的溶解度。用修正的Apelblat方程、λ方程、非随机双液(NRTL)方程和Wilson方程对溶解度进行了校正。根据Wilson方程计算了格列齐特的溶解吉布斯自由能、溶解焓和溶解熵。所获得的溶解度数据、热力学参数和溶出特性可为格列齐特结晶工艺的开发和优化提供参考。
The solubility of gliclazide in seventeen pure solvents, i.e. methanol, ethanol, n-propanol, i-propanol, n-butanol, i-butanol, s-butanol, acetone, cyclohexanone, ethyl formate, methyl acetate, ethyl acetate, acetonitrile, tetrahydrofuran,N,N-dimethylformamide, chloroform and toluene was determined using a gravimetric method over a temperature range from 278.15 to 318.15 K at atmospheric pressure. The obtained solubility was corrected by the modified Apelblat equation,λhequation, non-random two-liquid (NRTL) equation, and the Wilson equation. The mixing properties, such as the dissolution Gibbs energy, enthalpy and entropy of gliclazide, were calculated based on the Wilson equation. The solubility data, thermodynamic parameters and dissolution properties would be useful for the development and optimization of the crystallization processes for gliclazide in industry.
