Abstract

본 발명은 중금속 포집제로 널리 사용되고 있는 디티오카바메이트 화합물을 제조하는 새로운 방법에 관한 것으로, 폴리아민을 알칼리금속 수산물의 수용액상에서 상전 이촉매를 소량 사용하고 이황화탄소와 가압반응을 시킴으로써 간단하게 원하는 디티오카메이트 화합물을 제조할 수 있다.The present invention relates to a novel method for preparing a dithiocarbamate compound widely used as a heavy metal collecting agent. Mate compounds can be prepared.

본 발명에 따라, 종래의 방법에 의해 반응 시간이 획기적으로 단축되며, 이황화탄소가 100%치환이 가능하여, 저렴한 가격으로 경제성 있게 상기 디티오카바메이트 화합물을 제조할 수 있다.According to the present invention, the reaction time is drastically shortened by the conventional method, and 100% substitution of carbon disulfide is possible, so that the dithiocarbamate compound can be produced economically at a low price.
