We present evidence of hydrogen bond formation, not salt formation, as the driving force in the liquefaction of a solid pharmaceutical in the form of a neutral acid–base complex, as exemplified by the liquid formed from a mixture of the local anesthetic lidocaine with fatty acids; these complexes exist at the boundary between simple eutectics and partially ionised ionic liquids.
我们提出的证据表明,氢键形成(而非盐形成)是中性酸碱复合物形式的固体药物液化的驱动力,局部麻醉剂利多卡因与脂肪酸的混合物形成的液体就是一例;这些复合物存在于简单共晶与部分离子化离子液体之间的边界。
