摘要：NOVELTY - Low-temperature catalytic dechlorination of a chlorinated aromatic hydrocarbon comprises using hydrogen as a reducing agent in the presence of palladium (Pd), dripping alkaline dechlorinating reagent, and reacting the chlorinated aromatic hydrocarbon compound and hydrogen in an organic solvent to obtain phenol. The chlorinated aromatic hydrocarbon compound is monochlorinated or polychlorinated phenol. The catalyst comprises (wt.%) stable carrier (90-99), and Pd (1-10) in organic solution. The carrier is active carbon, silicon oxide, and/or alumina. USE - Method for low-temperature catalytic dechlorination of a chlorinated aromatic hydrocarbon (claimed). ADVANTAGE - The obtained phenol has high selectivity, and can be recycled. By simple filtering, the Pd catalyst can be recycled for many times without inactivation.
