Volumetric properties of room temperature ionic liquid 2 The concentrated aqueous solutions of {l-methyl-3-ethylimidazolium ethyl sulfate + water} in a temperature range of 278.2 K to 338.2 K

摘要

This paper reports measurements of densities of aqueous EMISE(l-ethyl-3-methylimidazolium ethyl sulfate)using a Westphal balance as a gravimetric technique in a temperature range of 278.2 K to 338.2 K.Values of the apparent molar volumes of aqueous EMISE were calculated and were treated by Pitzer-Simomson theory and Clegg-Pitzer theory,respectively.The values of Pitzer-Simomson parameters and Clegg-Pitzer parameters were obtained by fitting experimental data.
