Room Temp: 298 $\pu{K}$

Methodology:

The isothermal titration method was used. Phase equilibrium was determined by the secants method. Each secant represented a constant water-toluene mass ratio, the concentration of 1-propanol was variable. After 24 h separation, refractive indexes of both phases were measured. Equilibrium concentration of 1-propanol in both phases, in weight percent, was reported for 15 tie lines.

Sample Information:

1. Source not specified, chemically pure grade: used as received; BP = 97.4°C, $n_{D}^{20}$ = 1.3858.
2. Source not specified, pure for analysis grade; used as received; BP = 110.6°C, $n_{D}^{20}$ = 1.4967.
3. Freshly distilled water, $n_{D}^{20}$ = 1.3332.

Measurement Errors:

Ambient temperature: Temp. ±0.1°C.
Mass concentration (m/v) (1): Not reported.
