  • Aminoalcohol and biocide compositions for aqueous based systems
    Patent number: 9034929
    Abstract: Biocidal compositions and their use in aqueous media, such as metalworking fluids, the compositions comprising a biocidal agent; and a non-biocidal primary amino alcohol compound of the formula (I); wherein R1, R2, R3, R4, and R5 are as defined herein.
    Type: Grant
    Filed: December 13, 2007
    Date of Patent: May 19, 2015
    Assignee: ANGUS Chemical Company

  • CORROSION AND MICROBIAL CONTROL IN HYDROCARBONACEOUS COMPOSITIONS
    Publication number: 20120311922
    Abstract: Provided are additives of formula I for use in hydrocarbonaceous compositions, such as petroleum or liquid fuels: wherein R1, R2, R3, R4, and R5 are as defined herein. The additives improve the corrosion resistance of the compositions and, when the composition is biodiesel, also improve microbial resistance. The additives further enhance the antimicrobial efficacy of any added biocides contained in such compositions.

  • Method and composition for controlling microbial growth using bromontrostyene and peracetic acid
    Patent number: 5965617
    Abstract: The present invention provides a method and composition for controlling the growth of microorganisms in aqueous systems, such as industrial process waters. The method includes the steps of adding a synergistically effective amount of a biocide, 2-bromo-2-nitrostyrene ("BNS"), and an oxidant, peracetic acid, to industrial process waters to control microorganism growth. The composition of the present invention comprises a synergistically effective amount of a biocide, 2-bromo-2-nitrostyrene, and an oxidant, peracetic acid, to control microorganism growth. The method and composition of the present invention are particularly effective in the treatment of pulp and paper water processing systems.
