Robert J. Hanchar 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).

  • Patent number: 8829237
    Abstract: This invention provide processes for producing carboxylic acid product, along with useful salts. The carboxylic acid product that is produced according to this invention is preferably a C2-C12 carboxylic acid. Among the salts produced in the process of the invention are ammonium salts.
    Type: Grant

    Inventors: Robert J. Hanchar, Susanne Kleff, Michael V. Guettler
  • Publication number: 20130295627
    Abstract: Disclosed is a process for producing 2-methyl-3-buten-2-ol (MBO). The process is carried out by fermenting a hydrocarbon in a fermentation medium in the presence of a MBO-producing microorganism to produce the MBO. The MBO is removed from the fermentation medium to maintain a concentration of MBO non-toxic to the MBO-producing microorganism by flowing a gas through or across the fermentation medium to effectively remove at least a portion of the MBO into a vapor phase region of the fermentation medium. The rate of removal is measured according to the amount of MBO maintained in the vapor phase region, which is measured according to the vapor pressure of the MBO in the vapor phase region.

  • Patent number: 8431372
    Abstract: This invention is directed to methods of obtaining a high quantity of desired acid salt in a form that is relatively easy to recover. Particularly desired as a recovery product is an organic acid. A salt form of the desired organic acid is formed that is relatively high in concentration and that is relatively soluble in an aqueous medium. The method includes a step of fermenting a fermentable carbon source in the fermentation medium in the presence of a magnesium compound containing oxygen.

  • Patent number: 7204940
    Abstract: Disclosed are polymer-based coatings and materials comprising (i) a polymeric composition including a polymer having side chains along a backbone forming the polymer, at least two of the side chains being substituted with a heteroatom selected from oxygen, nitrogen, sulfur, and phosphorus and combinations thereof; and (ii) a plurality of metal species distributed within the polymer. At least a portion of the heteroatoms may form part of a chelation complex with some or all of the metal species. In many embodiments, the metal species are present in a sufficient concentration to provide a conductive material, e.g., as a conductive coating on a substrate. The conductive materials may be useful as the thin film conducting or semi-conducting layers in organic electronic devices such as organic electroluminescent devices and organic thin film transistors.
