  • Preparation of furfuryl alcohol from furfural
    Patent number: 4302397
    Abstract: A copper chromite catalyst having improved activity is prepared by forming a basic copper ammonium chromate complex in a known manner. The complex is decomposed by sintering at temperatures near 300.degree. C. to yield a copper chromite catalyst of improved activity. The copper chromite catalyst is especially useful in liquid phase production of furfuryl alcohol from furfural by hydrogenation. The hydrogenation reaction takes place at low pressure, e.g. under 30 atmospheres, due to the increased activity of the catalyst.
    Type: Grant
    Filed: August 20, 1980
    Date of Patent: November 24, 1981
    Assignee: Ashland Oil, Inc.
    Inventors: Leo J. Frainier, Herman Fineberg
