Abstract
Compositions are described which are useful in many applications such as fire extinguishing or refrigeration. The compositions may include a hydrochlorofluorocarbon such as 2,2-dichloro-1,1,1-trifluoroethane, a dispersant such as CF3I, and an inert gas such as argon, and may in some embodiments be held under pressure. For example, some fire extinguishing compositions may be composed of 2,2-dichloro-1,1,1-trifluoroethane, CF3I, and argon.
Claims7
A fire extinguishing composition, comprising about 92% to about 97% by weight 2,2-dichloro-1,1,1-trifluoroethane and about 3% to about 8% by weight CF3I based upon the weight of the composition without argon, and wherein the addition of argon results in a composition pressure of about 70 psig to about 150 psig at about 20° C.
A fire extinguishing composition, comprising about 94% to about 96% by weight 2,2-dichloro-1,1,1-trifluoroethane and about 4% to about 6% by weight CF3I based upon the weight of the composition without argon, and wherein the addition of argon results in a composition pressure of about 100 psig at about 20° C.
