Abstract: There is provided a method for rectifying a vinyl compound liquor. The method includes the steps of a) providing a rectification column operated at a temperature and pressure and b) feeding the vinyl compound liquor to be rectified into the rectification column, wherein the pressure of the rectification column and the temperature of the fed vinyl compound liquor are controlled, such that the temperature of the fed vinyl compound liquor ranges from its bubble point at the pressure of the rectification column to 10° C. lower than the bubble point.
