Patent ID: 7893178

Claim:
A process for storing a monomer phase which is liquid under the conditions of storage and whose content of the monomer is ≧95% by weight in a storage vessel, the monomer being a monomer from the group consisting of acrolein, methacrolein, acrylic acid, methacrylic acid, esters of acrylic acid and an alcohol having from 1 to 12 carbon atoms and esters of methacrylic acid and an alcohol having from 1 to 12 carbon atoms, and the liquid monomer phase having been obtained by condensation out of a gaseous phase or by melting of a crystalline phase, which comprises subjecting the liquid monomer phase, on the route from its generation into the storage vessel, to at least one separating operation to remove at least a portion of polymer of the monomer present dissolved in the liquid monomer phase.
