Abstract

The heat capacities in the temperature range (5 to 370) K and the parameters of solid-phase phase transitions and fusion were determined for three [Cnmim][NTf2] (n = 10, 14, 16) ILs. The temperature-dependent vapor pressures of [C14mim][NTf2] and [C16mim][NTf2] were measured with a a Knudsen effusion apparatus combined with a quartz crystal microbalance. Thermodynamic properties of these compounds in the crystal, liquid, and gas states were derived from the obtained data. The results obtained in this work were combined to those available in literature for the short-chain homologues to discuss regularities in thermodynamic properties of the series. While some properties demonstrate simple linear dependence on the alkyl chain length, a more complicated behavior with strong non-linearity or a break at n = 6 is observed for others.
