    摘要： Hydroxy ether carboxylates represented by the formula ##EQU1## wherein M is alkali metal, ammonium, alkyl ammonium or alkanol ammonium and A is hydrogen, methyl, ethyl, or CH.sub.2 OH, are useful as complexing agents and detergency builders. The ester and acid forms of such compounds are useful as intermediates for preparation of the salts.

    摘要： The present disclosure generally relates to a multicarboxylate, such as an alkyl alkoxy dicarboxylate a method of making the multicarboxylate, and methods to use the multicarboxylate. A specific embodiment of the disclosure is a compound comprising the chemical formula: R1-R2-R3, wherein R1 comprises a branched or unbranched, saturated or unsaturated, cyclic or non-cyclic, hydrophobic carbon chain having 7-150 carbon atoms; an oxygen atom linking R1 and R2; R2 comprises an alkoxylated chain comprising ethylene oxide, propylene oxide, butylene oxide, or a combination thereof; and R3 comprises a branched or unbranched hydrocarbon chain comprising 2-12 carbon atoms and 2-5 —COOH or —COOM groups wherein M is a monovalent, divalent, or trivalent cation. The composition has a variety of uses but in some embodiments may be used in enhanced oil recovery processes.
