  • Publication number: 20120286196
    Abstract: This invention covers a formulation providing protection against corrosion in liquid and vapor phase. Such formulations are used in applications where engine parts or fuel cell systems are subjected to a “running-in” or “hot-test” prior to final assembly or storage. The invention includes a concentrate as well as a dilute solution. The synergistic combination of inorganic ammonium derivatives in combination with monocarboxylic or dicarboxylic acids increases the period of protection. This enables storage for a longer period when the engine parts are shipped or stored prior to assembling. The use of the described invention pre-conditions the metal surface and provides protection even if afterwards the liquid is almost completely removed.

    Abstract: This invention covers formulation providing protection against corrosion in both the liquid and vapor phase. Such formulations are used in applications where engine parts or fuel cell systems are subjected to a “running-in” or “hot test” prior to final assembly or storage. The invention includes a concentrate as well as a dilute solution. The synergistic combination of inorganic ammonium derivatives in combination with monocarboxylic or dicarboxylic acids and a silicate dramatically increases the period of protection for both ferrous and aluminum alloys. This enables storage for a longer period when the engine parts are shipped or stored prior to assembling.

    Abstract: The sarcosine compounds used as a corrosion inhibitor according to the present invention include sarcosine and salt compounds thereof. The corrosion inhibitor is used in chemical mechanical polishing compositions or post CMP clean agents, which forms a protective film on the surface of a work piece to prevent the work piece from corrosion in chemical mechanical polishing, and thus common residue defect on the surface of a work piece due to the use of a conventional corrosion inhibitor (e.g. benzotriazole (BTA)) can be improved or the surface of a work piece can be protected from corrosion in post-CMP cleaning.

  • Publication number: 20080001125
    Abstract: Corrosion induced by the presence of naphthenic acids in hydrocarbon fluids, particularly where such fluids are at elevated temperatures, may be inhibited or controlled through use of corrosion inhibiting compositions comprising a combination of a minor portion of a phosphorus-based constituent and a major portion of a sulfur-based constituent, nitrogen-based constituent, or combination thereof. In another embodiment the sulfur-based constituent and/or nitrogen-based constituent may be used without any phosphorus-based constituent. Where the compounds are appropriately selected, the compositions may inhibit corrosion to a degree comparable or nearly comparable to the inhibition provided by an equal amount of some conventional phosphorus-based compounds alone, but are significantly less likely to impair catalyst activity in downstream cracking and refinery operations.
