METHOD FOR PRODUCING (METH)ACRYLIC ACID ESTER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a (meth)acrylic acid ester stably and efficiently over a long period of time by preventing distillation operation trouble in a low boiling point fraction-separating tower in which an esterification solution containing a (meth)acrylic acid ester obtained by reacting (meth)acrylic acid with alcohol in the presence of an acid catalyst is neutralized and washed and then an oil layer obtained by separating the resulting solution into an oil layer and a water layer is sequentially fed into a low boiling point fraction-separating tower and a purifying tower.SOLUTION: A water droplet capturing member is provided between an oil and water interface in the (meth)acrylic acid separation tower used for neutralization and washing and/or the still standing tank used for oil and water separation and a liquid extraction opening.
