Conditions:

Room Temp: 283 - 293 $\pu{K}$

Compiler:

A. Skrzecz

Methodology:

The analytical method was used. The two phase mixture was periodically shaken in a thermostated burette with water jacket for several hours. The phases were removed for analysis after separation. Methanol was determined by the Karl Fischer method. Water concentration in hydrocarbon-rich phase was smaller then 0.001-0.02%.

Sample Information:
  1. Source not specified, pure grade; distilled; contained <0.01% of water; $n^{20}$ = 1.3391.
  2. Source not specified; used as received; BP = 98.4°C, $n^{20}$ = 1.3877.
  3. Source not specified.
Measurement Errors:

Ambient temperature: Temp. ±0.05°C; soly. < ±1% (relative error of methanol concentration).
Mass concentration (m/v) (1): Not reported.

System Components:
  1. Methanol, $\ce{ CH4O }$; [67-56-1] NIST WebBook
  2. Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
  3. Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
