| Abstract: | The novel catalyst was prepared,PVPPdCl2FeSO4/Al-CLM-PEG,PVP(polyvinylpyrrolidone)-supported bimetallic PdFe and pillared montmorillonite function-allied by PEG(polyethylene glycol).It was shown that the catalyst had high activity and selectivity in water phase and could be easily separated and reused.The amount of HCOONa and reaction temperature and reaction time had a great influence on catalytic activity of the catalyst for dechlorination of aromatic chlorides. |
| Keywords: | PVP CLM aromatic chloride dehalogeration in water phase |
