Abstract
Abstract The use as a refrigerant or foam blowing agent of a 2-methoxy-1,1,1-trifluoroethane of the formula CF₃CH₂OCX₃ in which X each independently is F or H, optionally in combination with other refrigerants or blowing agents. The 2-methoxy-1,1,1-trrifluoroethane decomposes in the atmosphere without damage to the ozone layer.
