The azeotropic parameters in the 1,4-BG-C/sub 9/C/sub 15/ alcohol series at 13.33 kPa and the DEG-C/sub 9/-C/sub 16/ alcohol series at 2.67 kPa were experimentally determined. Azeotropy was experimentally studied in 14 1,4-BG-alcohol-hydrocarbon ternary systems. It was found that C/sub 8/ and C/sub 15/ alcohols are the alcohols with the lowest and highest molecular weights which form ternary azeotropes with 1,4-BG, and they are C/sub 8/ and C/sub 16/ alcohols for DEG. 1,4-BG is recommended as a separating agent for purification of hydrocarbons from the C/sub 17/-C/sub 20/ fraction of alcohols by the method of heteroazeotropic rectification.
