Lawrence M. Candela has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Production of hydrogen peroxide
    Patent number: 4975266
    Abstract: Hydrogen peroxide is produced by liquid phase molecular oxygen oxidation of methyl benzyl alcohol. Inhibiting impurities are removed prior to oxidation.
    Type: Grant
    Filed: December 27, 1989
    Date of Patent: December 4, 1990
    Assignee: Arco Chemical Technology, Inc.
    Inventors: Rajendra S. Albal, Robert N. Cochran, Lawrence M. Candela
  • Ethylbenzene oxidation
    Patent number: 4950794
    Abstract: The oxidation of ethylbenzene to products comprised of ethylbenzene hydroperoxide and acetophenone is modified in order to enhance acetophenone production by reducing the alkali content of the oxidation mixture below 0.1 ppm and by incorporation of 0.05 to 2 wt. % water in the oxidation mixture.
    Type: Grant
    Filed: May 24, 1989
    Date of Patent: August 21, 1990
    Assignee: Arco Chemical Technology, Inc.
    Inventors: Lawrence M. Candela, Robert N. Cochran, Scott H. Sandler
  • Production of hydrogen peroxide
    Patent number: 4897252
    Abstract: Hydrogen peroxide is produced by liquid phase molecular oxygen oxidation of methyl benzyl alcohol, water concentration in the reaction mixture being maintained below 4% by weight, more preferably below 2% by weight, and most preferably below 1% by weight.
    Type: Grant
    Filed: January 10, 1989
    Date of Patent: January 30, 1990
    Assignee: Arco Chemical Technology, Inc.
    Inventors: Robert N. Cochran, Lawrence M. Candela
  • Recovery of hydrogen peroxide
    Patent number: 4897085
    Abstract: A process is provided whereby the hydrogen peroxide-containing oxidate from methyl benzyl alcohol oxidation is contacted with ethyl benzene extractive solvent and a hydrogen peroxide phase is separated from a solvent phase which also contains methyl benzyl alcohol and acetophenone.
    Type: Grant
