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:
(1) Source not specified, pure grade; distilled; contained<0.01% of water; n(20°C)=1.3391.
(2) Source not specified; used as received; b.p.=68.7°C, n(20°C)=1.3753.
(3) Source not specified.
Estimated Errors:
Solubility: Not reported.
Temperature: Temp. ±0.05°C; soly.< ±1% (relative error of methanol concentration).
