Abstract
The problem solved by the present invention is to provide a method for efficiently purifying acrylic acid derivative (I), more specifically a method for efficiently eliminating alcohol (II) from a composition containing acrylic acid derivative (I) and alcohol (II). This problem is solved by a method for purifying an acrylic acid derivative represented by Formula (I): wherein R1 and R2 are identical or different, and each represents alkyl, fluoroalkyl, aryl that may have one or more substituents, halogen, or hydrogen, R3 represents alkyl, fluoroalkyl, aryl that may have one or more substituents, or hydrogen, and X represents alkyl, fluoroalkyl, halogen, or hydrogen,
