摘要：
A method for the decomposition of a Michael type adduct, characterized by causing a Michael type adduct to react in the presence of an N-oxyl compound thereby decomposing the Michael type adduct into acrylic acid and/or the acrylic ester and/or the alcohol and a method for the production of acrylic acid and/or the acrylic ester, characterized by comprising a step of recovering a Michael type adduct formed in the process for the production of acrylic acid or acrylic ester and a step of decomposing the recovered Michael type adduct by the method of decomposition mentioned above. This invention, therefore, allows promotion of efficient utilization of the raw materials.
