  • Catalysts for production of phenol and its derivatives
    Patent number: 5672777
    Abstract: Zeolite catalysts useful for the production of phenol and its derivatives by oxidative hydroxylation of benzene and its derivatives by nitrous oxide, e.g. at temperatures of 225.degree.-450.degree. C., having substantially enhanced process characteristics resulting from hydrothermal treatment using a gas containing from about 3 to 100 mole percent water vapor, e.g. in nitrogen, at a temperature ranging from about 500.degree. to 1000.degree. C. Two hours of hydrothermal treatment has been shown to be effective.
    Type: Grant
