ABSTRACT
The vapor pressures of binary mixtures containing methanol and ionic liquid 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [HMIM][NTf2] were investigated at temperatures ranging from 274.15 K to 413.15 K using the two different setups with static method. The activity coefficients ?i of methanol in the [HMIM][NTf2] and osmotic coefficients ?i of the [HMIM][NTf2] have been determined from the vapor liquid equilibria data and are described using the Clasius-Clapeyron and NRTL equation.
