Study On Catalytic Hydrodechlorination Of Aryl Chloride With Palladium-based Catalysts

1,3,5-trichlorobenzene with Pd(phen)Cl2, under the different temperature (303K、313K、323K、333K), the reaction substrate alomost be completed converted, and the higher the temperature, the faster the reaction rate could be reached;At the temperature in the range of 303K-333K, the conversion rate of 1,2,3-trichlorobenzene and 1,2,4-trichlorobenzene can also reach 90% in short time, as the steric effect, the reaction rate of 1,2,3-trichlorobenzene and 1,2,4-trichlorobenzene was faster than 1,3,5-trichlorobenzene; At the acid environment and normal temperature , under the effect of Fe nanoparticles, reaction conversion of chlorobenzene was unreacted; Under the effect of nano-Pd-Fe, the conversion rate of chlorobenzene was completed converted at short time. All the reaction was under the hydrogen atmosphere.
