mÉtodo para obter etanol de um a soluÇço de alimentaÇço

The present invention relates to a method for obtaining ethanol from a feed solution comprising: providing a feed solution comprising water and ethanol; providing an extractant that is immiscible with the feed solution, the extractant comprising a mixture of at least one alkane having a first yield factor for extraction of ethanol from the feed solution; and at least one secondary or tertiary branched aliphatic alcohol having from 6 to 12 carbon atoms, wherein the branched aliphatic alcohol has a second yield factor for extraction of ethanol from the feed solution, wherein the mixture has a third yield factor for extraction of ethanol from the feed solution, and further wherein the third yield factor is greater than both of the first and second yield factors, wherein the extractant has a boiling point greater than 150°C; contacting the extractant with the feed solution; and at least partially removing ethanol from the extractant.
