FIELD: chemistry.
SUBSTANCE: invention relates to a heat transfer composition. Composition comprises trifluoroethylene (HFO-1123) and at least one first compound selected from E-1,2-difluoroethylene, Z-1,2-difluoroethylene, 1,1-difluoroethylene, chlorotrifluoroethylene, E-1-chloro-1,2-difluoroethylene, Z-1-chloro-1,2-difluoroethylene, 1,1,2-trifluoroethane and methane. Total proportion of the first compound in the composition ranges from 0.0001 to less than 0.5 wt. % of the total amount of HFO-1123 and the first compound.
EFFECT: invention provides an HFO-1123 composition with a low global warming potential (GWP) and is suitable for wide application as a heat transfer agent, sprayed aerosol, blowing agent, gassing agent, solvent.
