| Abstract: | The liquid-liquid equilibrium data for tert-butanol-water-KFsystem were measured at 40 ℃,the effect of the mass ratio of aqueous potassium fluoride to aqueous tert-butanol on the dehydration rate is studied.The results showed that: When the mass ratio of the aqueous potassium carbonate with 60.00 % of mass fraction to the aqueous tert-butanol was 1.25,the dehydration rate was 80.73 %,tert-Butanol with 99.50 % of mass fraction could be distillated from the organic phase,the dilute potassium fluoride solution in aqueous phase could be recovered by evaporation and the recovered potassium fluoride solution coluld be recycled. |
