<p>A process for producing (meth)acrylic ester involving a step of washing and/or neutralizing a liquid reaction mixture containing (meth)acrylic ester and an oil-water separation step of separating an organic layer containing (meth)acrylic ester from a water layer formed in the washing and/or neutralization treatment, characterized in that it further comprises withdrawing a liquid containing the organic layer and the water layer. The method allows the prevention of troubles such as the clogging of a separation column in a low boiling point component separation step due to the deposition of a polymer or a sludge on a tray of the separation column or in a packed column or the clogging of a heating device due to the stick of foreigners therein, which leads to a stable operation of an apparatus for a long period of time.</p> |
