METHOD FOR PURIFYING ACRYLIC ACID ESTER COMPOUND

The present disclosure addresses the problem of providing a method for purifying an acrylic acid ester compound. This problem can be solved by a method for purifying a compound represented by formula (1)(wherein R1 and R2 are the same as or different and each represent an alkyl group, a fluoroalkyl group, an aryl group optionally having one or more substituent groups, a halogen atom, or a hydrogen atom, R3 is an alkyl group, a fluoroalkyl group, or an aryl group optionally having one or more substituent groups, and X is a fluoroalkyl group or a halogen atom), the method including step A of distilling composition A containing (a) the compound represented by formula (1), (b) an alcohol, and (c) a salt so as to obtain a concentrate containing the compound represented by formula (1).
