DISTILLATION METHOD FOR EASILY POLYMERIZABLE SUBSTANCE AND DISTILLATION APPARATUS USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a distillation method which makes the continuous operation of a distillation column possible by reducing the formation of a polymer in performing distillation of an easily polymerizable substance and a distillation apparatus. SOLUTION: This distillation method for the easily polymerizable substance comprises heating a reflux liquid in refining the easily polymerizable substance by distillation. This distillation apparatus has a heating means 1 for heating the reflux liquid. As a result, the vapor containing the easily polymerizable substance is prevented from condensing and therefore the continuous operation of the distillation column is made possible.
