Recovery of Alcohols from Dilute Solutions

I have recently found that Hexyl Acetate is a very good solvent for the liquid liquid extraction of alcohols from their dillute solutions.

This is possible because Hexyl Acetate is insoluble in water & have very good affinity for alcohols.

You can try it at lab scale for your system. However I feel that it will be good to use it if effluent is having >4% alcohol.

This will be much cheaper in comparison to distillation.

Hope it is useful for you........
You can add more solvents for such technologies.
