US Patent:

Filed:

Nov 17, 2008

Appl. No.:

12/272732

Inventors:

Donald E. Kiely - Missoula MT, US
Tyler N. Smith - Missoula MT, US

Assignee:

The University of Montana - Missoula MT

International Classification:

A01N 25/10
C08G 69/26
C08L 77/00
C08K 3/00

US Classification:

524 10, 524 9, 524 21, 524211, 504360, 528332

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.

Appl. No.:

12/422135

Inventors:

Donald E. Kiely - Missoula MT, US
Kirk R. Hash - Drummond MT, US
Tyler N. Smith - Missoula MT, US

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.

C09K 15/32

US Classification:

2523894, 252396, 25238962, 25238952, 25238954

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.
