Purification method of (meth) acrylate |
| abstract |
(57) [Problem] To provide an esterification reaction between (meth) acrylic acid and an alcohol in the presence of an acid catalyst to produce a (meth) acrylic acid ester, in the purification step, To provide a method for producing a high-purity (meth) acrylic acid ester by suppressing the production of alcohol by a transesterification reaction with a hydroxy compound as a side reaction product present as an impurity. SOLUTION: It is characterized in that a (meth) acrylic ester containing impurities is rectified in the presence of a heteroatom-containing chelate complex having an element of Groups 7 to 12 of the periodic table as a central metal. A method for purifying (meth) acrylic esters. |
