Abstract: This invention relates to novel corrosion inhibitors which are capable of sequestering metal ions such as calcium and magnesium and are derived in part from renewable carbohydrate feedstocks. The corrosion inhibitors are mixtures containing one or more hydroxycarboxylic acid salts and one or more suitable oxoacid anion salts.

Abstract: Compositions which inhibit corrosion and alter the physical properties of concrete (admixtures) are prepared from salt mixtures of hydroxycarboxylic acids, carboxylic acids, and nitric acid. The salt mixtures are prepared by neutralizing acid product mixtures from the oxidation of polyols using nitric acid and oxygen as the oxidizing agents. Nitric acid is removed from the hydroxycarboxylic acids by evaporation and diffusion dialysis.

Abstract: A method of producing high molecular weight stereoregular head, tail-poly(alkylene D-glucaramides) is described. Amidoamino acids are esterified in cold alcohol and then polymerized in a protic solvent to form steroregular prepolymers. The prepolymers are then further polymerized by dissolving them in a solvent to form larger, purer postpolymers. Compositions of matter prepared using the subject method are also described.

Abstract: High molecular weight random polyhydroxypolyamides (PHPAs) are produced by creating prepolymers which are further polymerized. Random prepolymers are formed from a stoichiometrically molar balance (1:1) starting material. The starting material is a 1:1 stoichiometrically balanced esterified aldaric acid:alkylene or alkylene derived diammonium salt. Alternatively, the starting material is an esterified stoichiometrically balanced diacid:diamine salt and a N?-ammoniumalkyl (or alkyl derived)-D-aldaramic acid terminal carboxylate zwitterionic salt mixture. The starting materials are polymerized in a basic alcohol using a second amine. The polymerized material, or the random prepolymers, are isolated and then further polymerized in a solvent, typically a mixed solvent of an alcohol and non-alcohol, to obtain the high molecular weight PHPAs.
