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-( eta -cyclopentadienyl)titanium dichloride and sodium tetrahydridoborate.

摘要： The chlorine or halide content in a chlorinated hydrocarbon or halogenated aromatic hydrocarbon in an environment which admits to the presence of air and moisture can be reduced by bringing the chlorinated hydrocarbon or halogenated aromatic hydrocarbon into contact with a 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 -cyclopentadienyl)titanium dichloride and sodium tetrahydridoborate. Optionally, the reaction is conducted in the presence of an aliphatic or aromatic amine, optionally in the presence of an inert organic solvent.
