When the end-point was reached, the mixture was left in the bath for 30 min before specific gravity and refractive index were determined. The binary two liquid-phase mixtures of toluene and water were treated with 1-propanol and when equilibrium was reached the samples of each layer were removed and refractive indexes were determined.
