Kogan, V. B.; Deizenrot, I. V.; Kulbyaeva, T. A.; Fridman, V. M.; Zh. Prikl. Khim. 29, 1387 (1956).
Variables:
Ambient temperature: 283 - 293 K

Method/Apparatus/Procedure:
The analytical method was used. The two phase mixture periodically shaken in a thermostated burette with water jacket for several hours. The phases were removed for analysis after separation. Methanol was determined by reaction with phthalic anhydride; water was determined by Karl Fischer method. Water concentration in hydrocarbon-rich phase was smaller than 0.01-0.02%.
Source and Purity of Materials:
- Source not specified, pure grade; distilled; contained<0.01% of water; n(20°C)=1.3391.
- Source not specified; used as received; b.p.=68.7°C, n(20°C)=1.3753.
- Source not specified.
Estimated Errors:
Ambient temperature: Temp. ±0.05°C; soly.< ±1% (relative error of methanol concentration).
Mass concentration (m/v) (1): Not reported.
