| 摘 要： | 重点介绍了离子液体表面活性剂的熔点与结构的关系。阳离子母体结构越不对称熔点越低，烷基链长增加熔点稍有提高；对阴离子型离子液体表面活性剂，阳离子的半径越大，其熔点越低；双子和Bola型离子液体表面活性剂比单疏水基离子液体表面活性剂的熔点高。室温呈液态的离子液体表面活性剂一般为黏稠液体，密度比一般有机溶剂大，在1 g/cm3左右，其表面张力为25~35 mN/m。

| Abstract: | The relationship between melting point and structure of ionic liquid surfactants was emphatically introduced. The higher degree of asymmetry of structure of the parent cationic group, the lower melting point of the ionic liquid surfactants. Melting point increases slightly with increase of chain length of the alkyl group. For anionic surfactants, the melting point decreases with the increase of the radius of the cation. The melting point of Gemini and Bola surfactants is higher than that of single-tail surfactants. Under ambient temperature, ionic liquid surfactants are viscous liquid with surface tension of 25-35 mN/m. In general, density of ionic liquid surfactants is about 1 g/cm3 and higher than that of conventional organic liquid chemicals. |
