The chlorination of 1,2-difluoroethane (HFC-152)

The photochlorination of CH2FCH2F yields CH2FCCl2F and CHClFCHClF, both of which were considered to be potential replacements for CFC-113 (CCl2FCF2Cl) based on their boiling points (48 deg C and 59 deg C, respectively).The CHClFCHClF/CH2FCCl2F ratio can be controlled by the choice of solvents.In aromatic solvents, the reactivity of the chlorine radical is reduced, increasing the amount of CH2FCCl2F produced.Relative rates in CCl4 and in the presence of water were compared to rates in aromatic solvents.Both CH2FCCl2F and CHClFCHClF failed in early toxicity tests and will thus not be pursued as HCFC replacements for CFC-113.
