Mutual Solubilities of the Systems of Halogenated Hydrocarbons-Alcohols-Water

Mutual solubilities of chlorobenzene-, chloroform-, and carbon tetrachloride-alcohol-water systems were measured at 30°. The systems of ethyl-, propyl-, and isopropyl-alcohol-water-chlorobenzene (chloroform), mono- and di-ethyleneglycol-water-chloroform, and tert-butyl alcohol-water-carbon tetrachloride belonged to the Type I with continued binodal curve, and others to Type II. Selective power of the halogenated hydrocarbons to alcohol was measured and the halogenated hydrocarbons were found to be a good solvent for extraction of alcohols, but not for mono- and di-ethylene glycols.
