Distillation of Ethanol-Water Solutions in the Presence of Potassium Acetate

Abstract Complete separation of ethanol-water mixtures through salt addition has been demonstrated in a continuously operated single sieve-plate-column including salt recycling. The effect of salt concentration as well as reflux ratio on the separation are outlined based on experimental data. The results clearly indicate that distillation in the presence of salts is an economical alternative to more conventional processes.
