Azeotropic composition |
| abstract |
It is not intended that the following abstract of the disclosure be construed as limiting the invention in any manner. The disclosure relates to binary azeotropic mixtures of tetrachlorodifluoroethane and methanol. It has also been discovered that n-butanol or isobutanol or sec-butanol will form azeotropes with these halogenated solvents. The disclosure also relates to ternary azeotropes of tetrachlorodifluoroethane and trichloroethylene with methanol. It has also been discovered that ethanol or isopropanol will also form ternary azeotropes with these two halogenated solvents. In a further embodiment ternary azeotropes are disclosed comprising tetrachlorodifluoroethane, trichloroethane and methanol. It has also been discovered that ethanol and isopropanol will also form ternary azeotropes with these two halogenated solvents. |
