Abstract



Miscibility of binary mixtures of benzyl benzoate and liquid paraffin as functions of temperature and composition has been determined using phase separation method. The binary mixtures demonstrated a critical (upper) solution temperature of 35 °C at 101325 Nm-2 with a mixing gap. A tie-line drawn at 28 °C across the phase diagram indicated that benzyl benzoate at concentrations between 38% and 77% remained practically immiscible with liquid paraffin due to phase saturation, while phase separation will occur in a solution containing a binary mixture of 25% benzyl benzoate in liquid paraffin stored at temperatures lower than 18 °C.

Keywords: Benzyl benzoate, liquid paraffin, binary mixtures, temperature-composition miscibility, phase diagram.
