Oxidative Decomposition of Chlorobenzene over Calcium-Deficient Hydroxyapatite

Article abstract of DOI:10.1246/bcsj.67.2454

Gaseous chlorobenzene was decomposed into CO and CO2 by the oxidative reaction at 400-450 deg C over calcium-deficient hydroxyapatite (DAp) prepared by an aqueous precipitation procedure.Phenol and benzene were not detected after the reaction.Most of the Cl in chlorobenzene was captured as Cl^- in DAp by the reaction.On the other hand, the DAp prepared by the hydrolysis of α-tricalcium phosphate was inactive for the decomposition of chlorobenzene.The difference in the activity between the two DAp materials was attributed to the difference of their crystallinities.
