1,1,1,2,3,3,3-heptafluoropropane (R 227ea) is a chemical compound from the group of fluorocarbons (PFCs).

properties

1,1,1,2,3,3,3-heptafluoropropane is a non-flammable colorless gas with an ethereal odor. At low concentrations there is only a slight warning effect. The gas is heavier than air and there is a risk of suffocation at high concentrations. As with all PFCs, decomposition in air - mainly in the case of fire - can form hydrogen fluoride . It has a critical temperature of 101.9 ° C, a critical pressure of 29.5 bar, a critical density of 0.592 g / cm³, a global warming potential of 3860 and an ozone depletion potential of 0.

use

1,1,1,2,3,3,3-heptafluoropropane is used as a refrigerant .
