Allyl alcohol ternary azeotropes with

Allyl alcohol forms an azeotropic mixture with water, and the mixture is a homogeneous liquid. Therefore, to obtain dry allyl alcohol, ternary azeotropic distillation and dehydration are required. [Pg.41]

Allyl alcohol (2-propen-l-ol, CH2=CHCH2OH, boiling point 96.9°, density 0.8520, flash point 25°C) is the simplest unsaturated alcohol and is a colorless corrosive liquid with a pungent odor. The vapor can cause severe irritation and injury to eyes, nose, throat, and lungs. Allyl alcohol is miscible with water and miscible with many polar organic solvents and aromatic hydrocarbons, but is not miscible with //-hexane. It forms an azeotropic mixture with water and a ternary azeotropic mixture with water and organic solvents. [Pg.39]
