| titleOfInvention | Method for purifying acrylic acid derivative |
| 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): n n n n n n n n n n whereinn nR 1 and R 2 are identical or different, and each represents alkyl, fluoroalkyl, aryl that may have one or more substituents, halogen, or hydrogen,n nR 3 represents alkyl, fluoroalkyl, aryl that may have one or more substituents, or hydrogen, andn nX represents alkyl, fluoroalkyl, halogen, or hydrogen,n the method comprisingn nstep A of bringing composition A containing the acrylic acid derivative represented by Formula (I) and alcohol represented by Formula (II):n nn R 4 —OH,n n wherein R 4 represents C 1-6 alkyl,n ninto contact with an acid anhydride to convert the alcohol into an ester compound that has a boiling point higher than the boiling point of the acrylic acid derivative represented by Formula (I). |
