  A first and second aspect of the invention relate to a process for producing a (meth)acrylic acid compound and a process for producing a (meth)acrylic ester, respectively. In particular, the second aspect of the invention relates to a process for (meth)acrylic ester production which includes a step in which by-products of a (meth)acrylic ester-yielding reaction are decomposed to recover a (meth)acrylic ester. A third aspect of the invention relates to a method of decomposing by-products of (meth)acrylic ester production in order to recover (meth)acrylic acid, a (meth)acrylic ester, and an alcohol through the decomposition of the by-products of (meth)acrylic ester production. A fourth and fifth aspect of the invention relate to a method of decomposing by-products of (meth)acrylic acid compound production in order to recover (meth)acrylic acid, a (meth)acrylic ester, and an alcohol through the decomposition of by-products of (meth)acrylic acid production and by-products of (meth)acrylic ester production.
