ABSTRACT:
An improvement in the process for the photochlorination of liquid mixtures of 2 to 6 carbon-containing aliphatic hydrofluorohalocarbons or hydrofluorocarbons and unsaturated hydrocarbons with ultraviolet light is disclosed. The improvement comprises using ultraviolet light emitted from an ultraviolet light source that delivers from about 0.01 to about 0.10 Einsteins per inch of arc at an input power of from about 0.50 to about 4.0 watts per inch of arc at a wavelength that is substantially the same as the wavelength absorption band of chlorine.
