Abstract

Klor- eller halogenidinnholdet i et klorert hydrokarbon eller et halogenert aromatisk hydrokarbon i et miljø hvor det kan finnes luft og fuktighet, kan reduse- res ved at det klorerte hydrokarbon eller det halogenerte aromatiske hydrokarbon bringes i kontakt med en reagens som om- fatter (i) et kompleks av et i hovedsak ikke-toksisk metall som har minst to oksy- dasjonstilstander og (ii) et reduksjons- middel som reduktivt farer komplekset fra kompleksets andre oksydasjonstrinn til det første oksydasjonstrinn. En representativ utførelse omfatter bis-(r75-cyklopentadie- nyl)-titan-diklorid og natriumtetrahydrid- borat. Eventuelt gjennomføres reaksjonen i nærvær av et alifatisk eller aromatisk amin, eventuelt i nærvær av et inert orga- nisk løsemiddel.The chlorine or halide content of a chlorinated hydrocarbon or halogenated aromatic hydrocarbon in an environment where air and moisture can be found can be reduced by contacting the chlorinated hydrocarbon or halogenated aromatic hydrocarbon with a reagent comprising (i. ) a complex of a substantially non-toxic metal having at least two oxidation states and (ii) a reducing agent which reductively passes the complex from the second oxidation step of the complex to the first oxidation step. A representative embodiment comprises bis- (r75-cyclopentadienyl) -titanium dichloride and sodium tetrahydride borate. Optionally, the reaction is carried out in the presence of an aliphatic or aromatic amine, optionally in the presence of an inert organic solvent.
