摘要: The chlorine content in chlorinated hydrocarbons in an environment which admits the presence of air and moisture can be reduced by bringing the chlorinated hydrocarbon into contact wih 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-(θ5-cyclopentadienyl)titanium dichloride and sodium tetrahydridoborate.
