Abstract:
The subject of the invention is a process for recovering/purifying a C 1 -C 4  (meth)acrylic ester from a crude reaction mixture comprising said ester, the process being carried out using a purification system comprising a divided wall column and a decanter, resulting in a simplification of the process and in a high productivity of the ester produced corresponding to the standards in terms of purity. The invention also relates to a process for producing C 1 -C 4  (meth)acrylic ester comprising this recovery/purification process.

Claim (Index 6):
A process according to  claim 1  wherein stabilization of the purification system is carried out using a single polymerization inhibitor, injected at the top condenser, the purified (meth)acrylic ester being withdrawn laterally from the divided wall column in the form of an already stabilized liquid or gas stream.
