ABSTRACT
The heat capacities of crystalline tetrabutylammonium iodide (TBAI) and tetra-phenylborate (TBATBPh) were determined over the 6-350 K range by adiabatic vacuum calorimetry, generally with an uncertainty of 0.2%. The experimental data were used to calculate the standard thermodynamic functions of TBAI and TBATBPh, namely, the heat capacity, enthalpy, entropy and Gibbs function at p = 0.1 MPa for the range from 0 to T = 350 K. The standard entropy of formation TBAI and TBATBPh at T = 298.15 K was also determined. Their melting as well as the polymorphic phase transition for TBATBPh were detected by DSC and their thermodynamic characteristics were determined.
