Abstract

공기 및 수분 존재를 허용하는 환경에서 염소화 탄화수소 또는 할로겐화 방향족 탄화수소중의 염소 또는 할로겐화물 함량은 염소화탄화수소 또는 할로겐화 방향족 탄화수소를 2개 이상의 산화상태를 갖는 실제로 비독성인 금속 착물(ⅰ) 및 착물을 제2산화단계에서 제1산화상태로 환원적으로 복원시키는 환원제(ⅱ)로 구성되는 시약과 접촉시킴으로써 환원 될 수 있다. 대표적인 실시양태는 비스-(n5-사이클로펜타디에닐) 티타늄 디클로라이드 및 나튜륨 테트라히드리도보레이트를 포함한다. 선택적으로, 본 발명의 반응은 지방족 또는 방향족 아민, 또는 불활성 유기용매의 존재하에 수행된다.The chlorine or halide content in chlorinated hydrocarbons or halogenated aromatic hydrocarbons in an environment that permits the presence of air and moisture can result in the formation of chlorinated hydrocarbons or halogenated aromatic hydrocarbons as substantially non-toxic metal complexes and complexes having two or more oxidation states. It can be reduced by contact with a reagent consisting of a reducing agent (ii) which reductively restores to the first oxidation state in the oxidation step. Representative embodiments include bis- (n 5 -cyclopentadienyl) titanium dichloride and naturium tetrahydridoborate. Optionally, the reaction of the present invention is carried out in the presence of aliphatic or aromatic amines or inert organic solvents.
