Abstract
A process for preparing a fluorinated product comprising: (a) reacting a molar excess of an aliphatic starting compound in liquid phase with fluorine in the presence of actinic radiation to produce a product mixture containing a fluorinated product having at least one hydrogen atom; and (b) recovering the fluorinated product from the product stream.

A process for preparing a fluorinated product comprising:
- (a) reacting a molar excess of an aliphatic starting material in liquid phase with elemental fluorine in the presence of ultraviolet radiation to produce a product stream containing a fluorinated product having at least one hydrogen atom, said starting material having the following formula:
- X—R—Y
- wherein:
- R is an unsubstituted or substituted C1-C10 divalent alkyl group having two or more hydrogens atoms;
- and
- X and Y are independently selected from Rh, F, or Cl, wherein Rh is a perhalogenated alkyl;
- and
- (b) recovering said fluorinated product from said product stream, said fluorinated product having the following formula:
- X—R′—Y;
- wherein:
- R′ is R with at least one hydrogen replaced by fluorine and at least one hydrogen remaining.
