Abstract
A method for producing an epoxyalkane includes the step of separating a stream containing an epoxyalkane and an extracting agent in a separation column having a column kettle reboiler. A part of a stream in the column kettle of the separation column enters an extracting agent purifier and is treated to obtain a gas phase light fraction that returns to the separation column and a liquid phase heavy fraction that is subjected to a post-treatment. The method can be used in the industrial production of an epoxyalkane.
