Patent ID: 7803964

Claim:
A method for synthesizing t-butyl (meth)acrylate by performing an addition reaction between isobutylene and (meth)acrylic acid in the presence of an acidic catalyst, the method comprising: (A) performing a dehydration decomposition reaction of t-butyl alcohol in the presence of a first acidic catalyst; (B) obtaining a crude t-butyl alcohol-containing isobutylene gas by separating at least water from a produced gas obtained in the step A to form the t-butyl alcohol-containing crude isobutylene gas; (C) absorbing the t-butyl alcohol-containing crude isobutylene gas in an absorption solvent containing (meth)acrylic acid; and (D) producing t-butyl (meth)acrylate by performing the addition reaction by bringing the absorption solvent which has absorbed the t-butyl alcohol-containing crude isobutylene gas into contact with a second acidic catalyst, wherein the t-butyl alcohol-containing crude isobutylene gas comprises 1% by mass or less of water.
