Abstract
The chlorine content in a chlorinated hydrocarbon in the presence or absence of air and moisture can be reduced by bringing the chlorinated hydrocarbon into contact with a dechlorination reagent which comprises (i) a complex of a substantially nontoxic metal having at least two oxidation states and (ii) a reducing agent which reductively returns the complex from its second oxidation step to its first oxidation stage. A representative embodiment involves bis-(.eta..sup.5 -cyclopentadienyl)titanium dichloride and sodium tetrahydridoborate.
