Variables:
Room Temp: 283 - 293 $\pu{K}$
Prepared by:
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; $n^{20}$ = 1.3391.
- Source not specified; used as received; BP = 68.7°C, $n^{20}$ = 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.
Components:
- Methanol, $\ce{ CH4O }$; [67-56-1] NIST WebBook
- Hexane, $\ce{ C6H14 }$; [110-54-3] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
