METHOD OF STORING MONOMER PHASE LIQUID UNDER STORAGE CONDITIONS Russian patent published in 2013 - IPC C07C51/42 C07C51/50 C07C57/07 C07C67/48 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of storing a monomer phase which is liquid under storage conditions. Described is a method of storing a monomer phase which is liquid under storage conditions, whose monomer content is ≥ 95%, in a storage vessel, the monomer being a monomer from a group consisting of acrolein, methacrolein, acrylic acid, methacrylic acid, esters of acrylic acid and an alcohol having 1-12 carbon atoms and esters of methacrylic acid and an alcohol having 1-12 carbon atoms, characterised by that the liquid monomer phase having been obtained by condensation from a gaseous phase or by melting of a crystalline phase, on the route from its generation into the storage vessel, is subjected to at least one filtration and/or centrifuging operation in order to separate at least a portion of the polymerisation product of the monomer dissolved in the liquid monomer phase.

EFFECT: preventing undesirable radical polymerisation during storage of the monomer phase.
