  • Corrosion inhibited chloride salt de-icers
    Patent number: 6149834
    Abstract: A novel chloride salt based de-icing composition comprising a corrosion inhibitor of a de-sugared sugar beet molasses. The corrosion inhibited de-icing compound comprises from 5 to 25 percent by weight of de-sugared molasses compared with the weight percent of the chloride salt in the de-icing composition.

  • Process for the preparation of 2,6-difluoroaniline
    Patent number: 5091580
    Abstract: 2,6-Difluoroaniline is prepared from 1,2,3-trichlorobenzene by partial fluorine exchange to a mixture of 2,6-difluorochlorobenzene and 2,3-difluorochlorobenzene, amination of the chloro substituents, and separation of the desired product from the isomeric 2,3-difluoroaniline. By incorporating a selective reduction into the process immediately after the partial fluorine exchange, the undesirable 2,3-difluorochlorobenzene is converted into valuable ortho-difluorobenzene and the 2,3-difluoroaniline isomer is avoided.

    Filed: March 27, 1991
    Date of Patent: February 25, 1992
    Assignee: DowElanco
    Inventors: R. Garth Pews, James A. Gall
  • Process and intermediates for the preparation of 2,6-difluoroaniline
    Patent number: 5041674
    Abstract: 1-Chloro-3,5-difluorobenzene is chlorinated to give 4,6-difluoro-1,2,3-trichlorobenzene which in turn is nitrated and reduced to the corresponding novel aniline, 2,6-difluoro-3,4,5-trichloroaniline. Further reduction of this aniline provides 2,6-difluoroaniline with high selectivity.

  • Preparation of fluorophenols
    Patent number: 4940821
    Abstract: Fluorophenols are prepared by heating a chlorofluorobenzene with water in the presence of a copper salt at a pH of from 3.0 to 6.5.
    Type: Grant
    Filed: March 20, 1989
    Date of Patent: July 10, 1990
    Assignee: The Dow Chemical Company
    Inventors: R. Garth Pews, James A. Gall
  • Preparation of 3,4-difluorobenzotrifluoride
    Patent number: 4937396
    Abstract: 3,4-Difluorobenzotrifluoride is prepared by contacting a 3,4-dihalobenzotrifluoride with an effective amount of KF or CsF in a polar aprotic solvent at an elevated temperature under substantially anhydrous conditions. The product can be removed as it is formed or the reaction may be run at the autogenous pressures generated by the reaction mixture in a sealed reactor.
    Type: Grant
    Filed: November 28, 1988
    Date of Patent: June 26, 1990
    Assignee: The Dow Chemical Company
    Inventors: R. Garth Pews, Jack C. Little, James A. Gall
  • Preparation of halofluorobenzenes
    Patent number: 4937397
    Abstract: Chlorofluorobenzenes and difluorobenzenes are prepared by contacting a dichlorobenzene with an effective amount of KF or CsF in a polar aprotic solvent at an elevated temperature under substantially anhydrous conditions. The product can be removed as it is formed or the reaction may be run at the autogenous pressures generated by the reaction mixture in a sealed reactor.
