Title:

METHOD FOR SEPARATING AND RECOVERING READILY POLYMERIZABLE SUBSTANCE FROM IMPURITY-CONTAINING READILY POLYMERIZABLE SUBSTANCE CONTAINING HIGH-BOILING SUBSTANCE AND APPARATUS THEREFOR

Document Type and Number:

Japanese Patent JP2003286202

Kind Code:

A

Abstract:

To provide a method for preventing polymerization when distillation operation is performed for recovering and separating a product from an impurity-containing readily polymerizable substance containing a high-boiling substance and an apparatus therefor.

The method is composed so as to prevent the polymerization by combining a batch distillation apparatus with a continuous distillation apparatus for recovering and separating the readily polymerizable substance from a solution of the impurity-containing readily polymerizable substance containing the high-boiling substance.
