Equipment type column to a polymerisable compound easily.

摘要

"Vase for a polymerisable compound easily.In a device for distillation, or device for decomposition reaction of acrylic acid, in which the liquid bottom of the column is heated in a refervedor (5) is supplied with a supply hole (1a) formed on the side wall of the main body of a column (1),A top plate (12a) is installed above the supply orifice (1a) and a collision plate (12b) to prevent liquid from bottom of the column spreads in the direction of the supply is suspended from the top plate (12a). The top plate (12a) is installed so that its upper surface is inclined downwards from the base end to the front end.According to the invention, the formation of a polymer due to the flow of liquid or gas heated by the refervedor inside the column can be inhibited by a simple mechanism, allowing in this way to the equipment in the column to operate for an extended period, stably and continuously.
