Abstract
Durability of the novel catalyst system for phenol synthesis by vapor phase oxidation of benzoic acid was investigated in detail. Although a n obvious deactivation was observed using the NiO-NiFe2O4-Na2O system, prominent results were obtained by the addition of V2O5 to the cataly st. More than 90% both in phenol selectivity and benzoic acid conversi on were maintained more than 100 h. The remarkable enhancement of cata lytic performance is considered to be derived from the facilitated reo xidation of active species by V2O5 in its redox cycle.
