Abstract

Highlights: [•] Densities and viscosities from 278.15 to 333.15K are reported for three binary (2,2,2-trifluoroethanol+an IL) systems. [•] TFE+[bmim][BF4] system presents positive V E values except for the highest mole fractions of TFE, at the highest temperatures. [•] TFE+[bmim][PF6] presents negative V E values except at the low TFE mole fractions for the lowest temperatures. [•] TFE+[bmim][NTf2] presents negative V E values for all the mole fractions and temperatures studied. [•] The three systems present negative viscosity deviations becoming less negative with increasing temperature.
