Abstract
The protic ionic liquid, 1,8-diazabicyclo[5.4.0]undec-7-en-8-ium trifluroacetate [DBUTFA], has been synthesized and densities of and speeds of sound in (DBUTFA + water) binary mixtures were measured simultaneously using a vibrating-tube digital density and speed of sound analyzer (Anton Paar, DSA 5000 M) at T = (293.15 to 328.15) K, with 5 K interval, and at atmospheric pressure. From the experimental density and speed of sound data, apparent molar volumes, \( V_{\phi } \), and apparent molar isentropic compressibilities, \( K_{S,\phi } \), were determined and further analyzed using Redlich–Mayer type equations to evaluate the corresponding infinite dilution apparent molar volumes, \( V_{2}^{\infty } \), infinite dilution apparent molar isentropic compressibilities, \( K_{S,2}^{\infty } \), and empirical parameters (SV, BV, Sk and Bk). The positive magnitude of the limiting volumetric slopes, SV versus m1/2 for this protic ionic liquid (PIL) in aqueous solutions, suggests that PIL–water interactions are weak.
