Method of production of compounds of (meth) acrylic

A method of producing (meth) acrylic which is a process for the production of (meth) acrylic acid or (meth) acrylic, by a step reaction comprising catalytic oxidation vaporde phase propylene, propane or isobutylene, characterized because at the time that a mixture of altopunto boiling containing a product Michael addition on a decomposition reactor for recuperaracidos (meth) acrylic lie is necessarily incorporates a liquid flow in the circumferential direction to a residuode liquid reaction decomposes in the decomposition reactor, the liquid reaction residue is removed, wherein the deliquido flow in the circumferential direction is incorporated in a liquid supplied from outside the reactor dedescomposicion.
