چکیده:

Ionic liquids (ILs) are a class of organic salts that are comprised entirely of ions have been considered as a novel replacement for many traditional organic compounds. Among the variousILs, the alkyl-sulfate derivatives have the great advantages that can be easily synthesized in a halide-free way at a reasonable cost with relatively low viscosityand is considered as a promising ILs in aqueous two phase systems. In this work, effect of various inorganic salts namely: K2HPO4,Na2SO4 and Na2CO3 on the phase separation of [emim][eSO4]-based aqueous two phase systemsare investigated at 288.15, 298.15K and 313.15K. The results showed that the order of the salt to phase sepration of [emim][eSO4]-based aqueous two phase systems is followed the order Na2CO3 > Na2SO4 > K2HPO4
