  • Patent number: 6372147
    Abstract: A process for the treatment of aqueous waste streams having a pH of 5 to 11 and containing organoboron compounds of the formula R4B−1M+ with hydrogen peroxide in order to convert such organoboron compounds to boric acid and organic compounds.
    Type: Grant
    Filed: May 7, 2001
    Date of Patent: April 16, 2002
    Assignee: E. I. du Pont de Nemours and Company
    Inventor: Ronald A. Reimer
  • Patent number: 5472680
    Abstract: A Process for the conversion of N.sub.2 O to NO by heating a gas stream containing N.sub.2 O by contact with a heated heat exchange surface to a temperature of about 400.degree. to 700 degrees C., and then heating the gas to a temperature of about 850 degrees C. while the gas is not in contact with a heated heat exchange surface, and spontaneously and decomposing the N.sub.2 O and recovering NO.
    Type: Grant
    Filed: January 26, 1994
    Date of Patent: December 5, 1995
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Ronald A. Reimer, Colin S. Slaten
  • Patent number: 5374767
    Abstract: Cyclohexyladipates are formed in a staged reactor, e.g. a reactive distillation column. A mixture containing a major amount of benzene and a minor amount of cyclohexene is fed to the lower portion of the reaction zone and adipic acid is fed to the upper portion of the reaction zone, cyclohexyladipates are formed and removed from the lower portion of the reaction zone and benzene is removed from the upper portion of the reaction zone. The reaction zone also contains an acid catalyst.

    Inventors: William C. Drinkard, Gerald C. Grunewald, Ronald Reimer
  • Patent number: 5206441
    Abstract: A process for the conversion of cyclohexyl hydroperoxide to cyclohexanone and cyclohexanol by turbulent high-intensity mixing with aqueous caustic containing a metal salt that accelerates the decomposition of cyclohexyl hydroperoxide.
    Type: Grant
    Filed: April 6, 1992
    Date of Patent: April 27, 1993
    Assignee: E. I. Du Pont de Nemours and Company
    Inventor: Ronald A. Reimer
  • Patent number: 4416824
    Abstract: A process for recovery of normally soluble triarylboranes in organonitriles by forming novel boron containing metal compounds, e.g., bis(triphenylborane-isocyano-N)-bis(adiponitrile)nickel (II).
    Type: Grant
    Filed: December 21, 1981
    Date of Patent: November 22, 1983

  • Patent number: 4336110
    Abstract: Separation of benzene from cyclohexane by distillation in the presence of selected nitriles.
    Type: Grant
    Filed: February 5, 1981
    Date of Patent: June 22, 1982
    Assignee: E. I. Du Pont de Nemours and Company
    Inventor: Ronald A. Reimer
  • Patent number: 4134923
    Abstract: Process for producing an alkali and/or alkaline earth metal hydroxide adduct of a triarylborane from the amine adduct thereof which comprises reacting an aqueous mixture of said amine adduct with an alkali and/or alkaline earth metal hydroxide at elevated temperature, e.g., 60-130.degree. C, removing substantially all of the amine liberated during the reaction, e.g., by stripping with an inert gas and thereby forming the metal hydroxide adduct of said borane. The process is preferably applied to the ammonia adduct of triphenylborane which adduct is generated in the treatment of a waste stream from the hydrocyanation process. Sodium is the preferred metal because the sodium hydroxide adduct is an intermediate in the production of triarylboranes which are useful as catalyst promoters.
