Appl. No.:

10/734418

International Classification:

C08G063/685
C08G283/04
C08G069/28

US Classification:

527312, 528335, 528336, 528351, 525540, 525926

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.

US Classification:

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.

US Classification:

Abstract:

A controlled nitric acid process employing oxygen and nitric acid as co-oxidants is used to oxidize organic compounds subject to nitric acid oxidation, to their corresponding carboxylic acids. Oxidation of some carbohydrates by this process can produce one or more of their corresponding acid forms. The process is carried out at moderate temperatures, typically in the range of 20 C. to 45 C. in a closed reactor, with oxygen gas being introduced into the reaction chamber as needed in order to sustain the reaction. Computer controlled reactors allow for careful and reproducible control of reaction parameters. Nitric acid can be recovered by a distillation/evaporation process, or by diffusion dialysis, the aqueous solution made basic with inorganic hydroxide, and the residual inorganic nitrate removed using a filtration (nanofiltration) device. The method eliminates issues of thermal control of the oxidation, release of nitrogen into the atmosphere, and post-reaction difficulties in the removal of nitric acid and inorganic nitrates.

Abstract:

Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.

International Classification:

C09K 3/18
C08B 37/02

US Classification:

252 70, 536112

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.
