    摘要: A corrosion inhibiting composition for aqueous brine water containing dissolved oxygen therein is prepared by the reaction of a carboxylic acid containing from 1 to 48 carbon atoms with a polyamine having the structure H2N(-R-NH)xH where R is an alkylene group containing from 2 to 6 carbon atoms and x is a small whole number greater than 1.

    摘要: Phosphated surface active hydroxy amines obtained by reacting polyphosphoric acid and/or phosphorus pentoxide with surface active hydroxyamines, e.g., C8 to C18 amines, with or without one or more hydroxy hydrocarbons, with or without neutralization, are used as scale inhibitors in brines, especially in oil wells, where calcium and barium salts are present.
