CATALYST FOR PRODUCTION OF PHENOL, ITS PRODUCTION AND PRODUCTION OF PHENOL

摘要

PURPOSE:To increase the rate of conversion of benzoic acid and the selectivity of phenol and to enhance the space time yield of phenol by the increased rate and selectivity. CONSTITUTION:Iron oxide, nickel oxide, an alkali metal compd. and an alkaline earth metal compd. are contained in a catalyst. When this catalyst is produced, iron oxide and nickel oxide are calcined at about 600-900 deg.C before or after the alkali metal and alkaline earth metal compds. are added. Benzoic acid is subjected to vapor phase oxidation in the presence of the catalyst to produce phenol.
