离子液体是一类在室温或接近室温条件下呈液态的盐,被称为“可设计的溶剂”。与传统溶剂相比,离子液体具有更好的热稳定性、不易挥发性、高导电性和催化性,强溶解能力,应用广泛,然而黏度高是其明显的缺陷。众所周知,有机硅拥有较好的疏水能力和表面能力,将其与离子液体相结合,合成黏度低的含硅离子液体,已成为离子液体发展的一个不容忽视的重要方向。综述了含硅离子液体的合成和应用进展。
Generally speaking,ionic liquid,also called “designed solvent”,is a sort of salt that appears liquid under the condition of room temperature or approaching room temperature.Compared with traditional solvents,ionic liquids perform better thermostability,nonvolatile property,high conductivity,catalytic property and strong solubility,therefore have been widely used.But ionic liquids also have obvious disadvantage—high viscosity.As known to all,silicone possesses better hydrophobicity and surface ability.The synthesis of low viscosity silicon-containing ionic liquids is an important direction in the progress of ionic liquids that can't be ignored.The synthesis and application progress of silicon-containing ionic liquids was focused.
