Notes:
a
Critical point of solubility.
Method/Apparatus/Procedure:
The titration method was used to determine binodal curve. The synthetic method was used to determine phase equilibra. The mole fraction of hydrocarbon in the charge before separation was about 0.30. After separation phases were analyzed by glc to determine methanol and hydrocarbon; concentration of water was determined by Karl Fischer method.
