Abstract The ionic liquid keeps its liquid state at or near room temperature.As one of the most promising green solvents,the ionic liquid has characteristic of low melting point,low vapor pressure,wide electrochemical window,adjustable acidity,strong solubility and high viscosity and is widely used in separation,organic synthesis and catalytic reaction.Room temperature ionic liquid has attracted industrial interests because it is environmentally friendly catalysts as novel green solvents.
