FIELD: chemistry.

SUBSTANCE: invention relates to a method of transferring heat to a liquid mixture containing at least one (meth)acrylic monomer selected from a group comprising acrylic acid, methacrylic acid, hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxypropyl acrylate, hydroxypropyl methacrylate, glycidyl acrylate, glycidyl methacrylate, methyl acrylate, methyl methacrylate, n-butyl acrylate, isobutyl acrylate, isobutyl methacrylate, n-butyl methacrylate, tert-butyl acrylate, tert-butyl methacrylate, ethyl acrylate, ethyl methacrylate, 2-ethylhexyl acrylate and 2-ethylhexyl methacrylate, through an indirect heat exchanger on whose primary side a fluid heat carrier flows and on whose secondary side simultaneously flows said liquid mixture containing at least one (meth)acrylic monomer, wherein the liquid mixture containing at least one (meth)acrylic monomer, in order to reduce contamination, additionally contains at least one active compound other than (meth)acrylic monomers which is selected from a group consisting of tertiary amines, salts formed from a tertiary amine and a Bransted acid, and quaternary ammonium compounds, under the condition that none of the tertiary and quaternary nitrogen atoms in the at least one active compound bears a phenyl group but at least some of said tertiary and quaternary nitrogen atoms bear at least one alkyl group.

EFFECT: improved method.
