摘要：NOVELTY - Low-temperature catalytic dechlorination of chlorophenol comprises taking hydrogen as reducer and palladium (Pd) catalyst, and dripping alkali dechlorination agent; and reacting chlorinated aromatic hydrocarbon compound with hydrogen in organic solvent to obtain phenol. The chlorinated aromatic hydrocarbon compound is monochlorosubstituted or polychlorosubstituted phenol. The catalyst is carrier for stabilizing organic solvent and metal Pd. The carrier consists of market active carbon, silicon oxide and aluminum oxide (90-99 wt.% of total catalyst). The Pd content of Pd catalyst is 1-10 wt.%. USE - Method for low-temperature catalytic dechlorination of chlorophenol (claimed). ADVANTAGE - The method provides with excellent industrial prospect for environmental protection. The palladium catalyst can be repeatedly used without inactivating by filtering in a simple way.
