With the dissolubility organic high polymer loading palladium complex compound takes the role of catalyst, an atmospheric hydroprocessing dehalogenation reaction is conducted in the organic solution at 20-65℃ with inorganic alkali(NaOH) in it. The temperature, dissolvent, the quantity of dissolvent and alkali of the dehalogenation reaction and their influences to the reactive degree are studied. The results prove that loading palladium complex compound effects as a catalyst can get high catalyzing efficiency. It has a simple reactive system without side reactions and is a fine method to get halohydrocarbon hydrogenate dehalogenation, and it has a wide applied perspective in organic industry and environmental protection.
