Abstract:
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--Ywherein:R is an unsubstituted or substituted C.sub.1 -C.sub.10 divalent alkyl group having two or more hydrogens atoms; andX and Y are independently selected from R.sub.h, F, or Cl, wherein R.sub.h 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.
