  • Patent number: 12077486
    Abstract: The invention relates to specific quaternary amidoamine detergents, the process to make them, and their use. The quaternary amidoamine detergents are obtainable by reacting a multifunctional acid with an amino amine, followed by quaternization, suitably with dimethyl carbonate, and subsequent reaction with a fatty acid. In the process to make the quaternary amidoamine detergents a multifunctional fatty acid is reacted with an amino amine, typically an amino alkylene amine, followed by quaternization with a quaternizing agent and subsequent replacement of the anion of said quaternizing agent with a fatty acid anion. The quaternary fatty amidoamine detergents are particularly useful as a surface-active compound that is soluble in an a-polar medium, for example when used as a stabilizer for solids in an a-polar medium.

  • Patent number: 8833450
    Abstract: The present invention relates to nitrogen-containing hydroxyethyl substituted compounds to be used as corrosion inhibitors for metal surfaces, for example in aqueous systems and in particular in oil-field applications, e.g. in oil or gas wells, and which could be used under sweet-well conditions as well as under sour-well conditions. It may also be used in oil-field acidizing and fracture-acidizing well stimulation treatment. The compounds belong to the group of partly ethoxylated fatty alkylamines, partly ethoxylated alkyletheramines and partly or fully hydroxyethyl substituted alkylamidopropylamines.

  • Patent number: 8709169
    Abstract: The present invention relates to the use of an alkyl di(lower alkyl)mono(polyoxyethylene) quaternary ammonium compound as a hydrotrope in 5 aqueous solutions for a nonionic surfactant, preferably a C8-C18-alcohol alkoxylate containing 1-20 ethyleneoxy units and 0-5 propyleneoxy units. It also relates to a composition comprising said quaternary ammonium compound and said nonionic surfactant. The cationic surfactant has the formula 10 R2+R(1)N(CH2CH2O)n H X R1 wherein R?C6-C22 alkyl; R1 and R2 are independently a C1-C4 alkyl group; n=8-25; and X? is an anion. The compositions may be used for the cleaning of hard surfaces, for example for vehicle cleaning or machine dishwashing.
