【発明の名称】ポリ塩化ビフェニルの分解法
Document Type and Number:
Japanese Patent JPH04500476
Kind Code:
A
Abstract:
Polychlorinated biphenyls are chemically degraded by contact with a Lewis acid catalyst in a non-aqueous liquid medium, in the presence of a cation which combines with the chlorines on the PCBs to form a solid chloride of the cation which will precipitate out from the liquid medium. Preferred Lewis acids are metal halides, particularly a combination of aluminum chloride and ferric chloride, and the preferred cation is potassium in the form of potassium hydroxide. The process is susceptible to both batch and continuous operation.
