Microwave-enhanced dechlorination of chlorobenzene

Microwave-enhanced dechlorination of chlorobenzene - Heterogeneous liquid-phase dechlorination of chlorobenzene over supported palladium-based catalysts to form benzene was examined using microwave and conventional heating methods. The reaction was carried out in a solution of NaOH in 2-propanol at atmospheric pressure and reflux temperature (approx. 83°C). Two types of commercial aluminium-silicate and γ-alumina-supported catalysts have been tested. The results obtained under microwave (MW) and conventional (CH) conditions were compared with respect to the rate enhancement, selectivity and catalyst activity. The sole product of the chlorobenzene dehalogenation was benzene. The effect of the addition of NaOH has been analysed for the neutralisation of HCl. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

- Heterogeneous liquid-phase dechlorination of chlorobenzene over supported palladium-based catalysts to form benzene was examined using microwave and conventional heating methods. The reaction was carried out in a solution of NaOH in 2-propanol at atmospheric pressure and reflux temperature (approx. 83°C). Two types of commercial aluminium-silicate and γ-alumina-supported catalysts have been tested. The results obtained under microwave (MW) and conventional (CH) conditions were compared with respect to the rate enhancement, selectivity and catalyst activity. The sole product of the chlorobenzene dehalogenation was benzene. The effect of the addition of NaOH has been analysed for the neutralisation of HCl.
