Abstract
A method for producing epoxyalkane includes the step of separating, in a separation column, a stream containing epoxyalkane, extractant, and diol. The separation column operates under conditions so as to enable the extractant and the diol to form an azeotrope, and a stream containing extractant and binary azeotrope is extracted from the side-draw of the separation column to liquid-liquid separation. The method can be used for the industrial production of epoxyalkane.
