Method for producing easily polymerizable compound

Abstract

The present invention provides a method for efficiently obtaining a high-quality product. The present invention relates to a method for producing an easily polymerizable compound, the method using a purification apparatus including a wash column and at least one of a crystallization tank or a ripening tank, the crystallization tank forming easily polymerizable compound crystals from an easily polymerizable compound-containing solution or a mother liquor in an easily polymerizable compound crystal-containing slurry, the ripening tank growing the easily polymerizable compound crystals, the purification apparatus further including a line that includes a bend having a ratio R/D of radius R of curvature to line inner diameter D of more than 4 and not more than 10 and that is connected to at least one selected from the group consisting of the crystallization tank, the ripening tank, and the wash column, the method including sending the easily polymerizable compound crystal-containing slurry through the line.
