Physical properties ozone depletion potential

Table 14.4 lists the names and compositions of the fluorinated hydrocarbon solvent blends that were used in the past for cleaning applications. New replacement fluorinated solvents that have zero ozone depletion potential are also listed in Table 14.4. The physical properties of all the fluorinated solvents and blends are listed in Table 14.5. 1,1,2-Trichlorotrifluoroethane (CFC 113) has poor solvency for the soils normally encountered in cleaning operations. The patented Freon formulations from DuPont utilize CFC blends containing acetone, methanol, ethanol, isopropanol, and methylene chloride (Table 14.4)...
