Thermophysical, Cohesive Energy Density and Molar Heat Capacity of Surfactant-Based Low-Transition-Temperature Mixtures
The present investigation deals with the synthesis and thermophysical evaluation of six natural low-transition temperaturemixtures (NALTTMs) with surfactants as suitable hydrogen bond donors (HBDs) and ammonium salts as hydrogen bond acceptors (HBAs). Therrnophysical evaluation of these NALTTMs reveals the linear relationship of density- and refractive index and nonlinear relation of conductivity and viscosity with emperature. The obtained results are associated with temperature by binary model equations. Additionally, the molar heat capacity and cohesive energy density- manifest close dependence on the corresponding molar mass and follow a linear relation with increasing temperature. It could be concluded from the data that the choice of HBA and HBD with their respective molar ratio has a major influence on the extraction ability and thermophysical properties of NALTTM
