The present disclosure provides a gas liquefaction separator, a gas liquefaction recovery system, and a method for separating and recovering ethylene oxide. The gas liquefaction separator includes a housing, a blocking plate, a gas baffle, and a liquid collector, the latter three being located inside the housing. The liquid collector—an outer edge of which is connected to an inner wall of the housing—is located below the gas baffle, which is located below the blocking plate. The liquid collector includes a first flow guide surface, on a bottom portion of which is disposed a first hole. The gas baffle—an upper surface of which forms a second flow guide surface and an outer edge of which has a protrusion(s)—is connected to the first flow guide surface through the protrusion(s), thereby forming a second hole between the outer edge of the gas baffle and the first flow guide surface.

The present invention relates to tiglien-3-one compounds and their use in methods of treating or preventing protozoal infections, bacterial infections, parasitic infections and cell proliferative disorders. The tiglien-3-one compounds are also used in methods of controlling pests in humans, animals, plants and the environment

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.

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.
