| titleOfInvention | Process for the purification of acrylic acid derivatives |
| abstract | An object of the present invention is to provide a method for efficiently purifying an acrylic acid derivative (I), specifically, to provide a method for efficiently purifying the acrylic acid derivative (I) and alcohol (II) from a composition containing the acrylic acid derivative (I) and alcohol (II). Method for alcohol (II) removal. The above-mentioned problems are solved by a method for purifying an acrylic acid derivative represented by the following formula (I), which comprises containing an acrylic acid derivative represented by the following formula (I) and a formula (II): R 4 —OH The step A of converting the above-mentioned alcohol into an ester compound having a boiling point higher than that of the acrylic acid derivative represented by the above-mentioned formula (I) is carried out by contacting the composition A of the alcohol shown with an acid anhydride. In formula (I), R 1 and R 2 are the same or different, and represent an alkyl group, a fluoroalkyl group, an aryl group that may have one or more substituents, a halogen atom or a hydrogen atom; R 3 represents an alkyl group, a fluoroalkyl group An alkyl group, an aryl group which may have one or more substituents, or a hydrogen atom; X represents an alkyl group, a fluoroalkyl group, a halogen atom or a hydrogen atom. In formula (II), R 4 represents an alkyl group having 1 to 6 carbon atoms. |
