摘要：
An object of the present invention is to provide a method for efficiently eliminating water from a composition containing an acrylic acid derivative and water. This problem is solved by a method for eliminating water from a composition A containing: (A) 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; and (B) water, the method comprising step A of bringing the composition A into contact with a zeolite.
