1,2-Trichloro-1,2,2-trifluoroethane is widely used in industry for cleaning and degreasing solid surfaces. However, this substance is a type of perhalogenated chlorofluorocarbon (CFC) that can attack and damage stratospheric ozone, and thus alternative substances that have little or no destructive effect on ozone in the near future (eg 1, 1-dichloro-1-fluoroethane).

However, it is necessary to stabilize the azeotropic composition so that methanol does not attack the metal and produce hydrogen.

US Patent No. 4,8
42,764 uses secondary and tertiary amines, olefins and cycloolefins, alkylene oxides, sulfoxides, sulfones, nitrites and nitrites and acetylenic alcohols or acetylenic ethers for the stabilization of this azeotropic composition. Other possible compounds are listed.

It has been found that 3-dioxolane is an excellent stabilizer of the F141b / methanol composition. In fact, these substances can suppress the reaction of methanol with light metals such as aluminum and magnesium (which are very sensitive) and in this respect are very similar compounds (eg dimethoxyethane, diethyl ether, methyl). T-butyl ether, furan and tetrahydrofuran) exhibit very different performance.

A particularly preferred composition is one in which each weight ratio of methanol and F141b substantially corresponds to an azeotropic composition, ie 3-5% by weight of methanol,
