| titleOfInvention | Dehydration of alcohols |
| abstract | The present invention relates to a continuous process for producing substantially anhydrous alcohols from aqueous solutions thereof by distilling a mixture of aqueous alcohol and an entrainer FED to a drying column withdrawing an azeotrope as a distillate and continuously recovering anhydrous alcohol with less than 0.1 % by weight of water from the base of the drying column. The improvement resides in feeding the distillate to a condenser and introducing (a) the condensate therefrom in a substantially non-turbutent state into a decanter at a point close to the interface between the aqueous and organic phases present therein and (b) a specified amount of water, which is less than 0.25 volumes per volume of the anhydrous alcohol recovered, into the drying column at a point adjacent to that at which the organic hydrocarbon phase is returned as reflux. |
