  • Process for treating metals using anti-corrosion agents and corrosion inhibitors containing lactobionic acid amides
    Patent number: 5795851
    Abstract: A process for inhibiting the corrosion of metals, in which the metals are treated with anti-corrosion agents, corrosion inhibiting agents or metal treating agents which are composed of or which contain lactobionic acid N-alkylamides and/or lactobionic acid alkylamine amides and/or di-lactobionic acid alkyl diamides, in which the saturated or unsaturated alkyl group bonded to the amide function has a chain length of more than 18 carbon atoms.
    Type: Grant
    Filed: August 8, 1997
    Date of Patent: August 18, 1998
    Assignee: Solvay Deutschland GmbH
    Inventors: Klaus Gerling, Helge Rau, Kornelia Wendler, Karlheinz Uhlig
  • Corrosion preventing composition comprising lactobionic acid amides
    Patent number: 5779939
    Abstract: Corrosion prevention compositions which contain lactobionic acid N-alkylamides, and further having a pH below 9.0, are described. In particular, lactobionic acid N-alkylamides in which the saturated or unsaturated alkyl group bonded via the amide function has a chain length of 8 to 18 carbon atoms show a good corrosion-inhibiting action. The use of lactobionic acid N-alkylamides in corrosion prevention compositions and metalworking compositions is also described.
    Type: Grant

  • Process for production of aldobionic acid amide
    Patent number: 5644042
    Abstract: A process for the preparation of aldobionamides directly from an aldobionic acid starting material, in which an aldobionic acid is reacted by removing water by azeotropic distillation to obtain an aldobionolactone. The aldobionolactone can then be reacted with amines without further purification or isolation steps to obtain the aldobionamide.
