METHOD OF DISTILLATION FOR LIQUID INCLUDING MATERIAL LIABLE TO POLYMERIZE

摘要

PROBLEM TO BE SOLVED: To provide a method of distillation capable of inhibiting polymerization in a distillation apparatus in distillation of a liquid including material liable to polymerize such as a (meth)acrylic acid and a (meth)acrylate. SOLUTION: One or more condensers are installed in serial to a condenser installed on the exit side of a distillation tower in this method of distillation for a liquid including a material liable to polymerize, and the material liable to polymerize included in the vapor discharged from the upstream condenser is condensed by the downstream side condenser.
