Comparison of the behavior of the speed of sound versus the temperature for the proposed model and literature models for four members of the DES family having benzyl tributyl ammonium chloride as the HBA and the different HBDs of ethylene glycol (DES4) (A), diethylene glycol (DES5) (B), triethylene glycol (DES6) (C) and glycerol (DES7) (D). Experimental data o, proposed model ―, Haghbakhsh et al.’s model [24] ---, Gardas and Coutinho’s model [27] ― ―, Hekayati and Esmaeilzadeh’s model [28] · – · – and Singh and Singh’s model [29] ···.
