Patent

CA 2431190

Sulfated dicarboxylic acids, amine salts thereof, or inorganic salts thereof may be used in various applications, including use as corrosion-inhibiting additives (e.g., in oil-field drilling applications and in metalworking applications), as emulsifiers (e.g., in metalworking applications), and as lubricity-enhancing additives (e.g., in metalworking applications). Suitable sulfated dicarboxylic acids include sulfated cyclic dicarboxylic acids, as well as their amine salts or inorganic salts, according to the formula: (See Formula I) wherein: (a) x and y each independently represents an integer from 3 to 9, wherein x and y together equal 12; (b) Z represents a moiety selected from the group consisting of hydrogen and COOM, wherein at least one Z is hydrogen and one Z is COOM; (c) W represents a moiety selected from the group consisting of hydrogen and -O-SO3M, wherein at least one W represents -O-SO3M; and (d) M represents a member selected from the group consisting of hydrogen, an inorganic ion, or an amine radical, wherein each M may be the same or different. In some examples, at least one M may constitute an alkanolamine radical, such as a triethanolamine radical, a diglycolamine radical, a monoethanolamine radical, and an isopropanolamine radical, or an alkali metal ion, such as sodium ions and/or potassium ions.
