Water elimination method
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): whereinR 1 and R 2 are identical or different, and each represents alkyl, fluoroalkyl, aryl that may have one or more substituents, halogen, or hydrogen,R 3 represents alkyl, fluoroalkyl, aryl that may have one or more substituents, or hydrogen, andX represents alkyl, fluoroalkyl, halogen, or hydrogen; and(B) water,the method comprisingstep A of bringing the composition A into contact with a zeolite.
