Appl. No.:

11/065505

Inventors:

Eric C. Ward - Cookeville TN, US
Michael L. Standish - Chattanooga TN, US
Ivonne C. Weidner - Hixson TN, US

Assignee:

Akzo Nobel N.V. - Arnhem

International Classification:

C23F 11/16

US Classification:

252395, 558235, 558243

Abstract:

Alternative inhibitors that offer an improvement over tolyltriazole in inhibiting yellow metal corrosion. The dithiocarbamate compounds and their salts were compared to that of tolyltriazole under identical conditions. These comparative tests were conducted in common corrosion testing systems, using both electrochemical corrosion cells and pilot cooling rigs, using various water conditions. The test methods included electrochemical studies such as linear polarization resistance, open circuit potential versus time, Tafel and cyclic polarization.

International Classification:

C11D 337
C11D 310

US Classification:

510361

Abstract:

Maleate copolymers comprise less than 1% residual total free monomer and have a weight average molecular weight of 1,000 to 4,000. The copolymer comprises at least 50 mole percent maleate, 10 to 50 mole percent acrylate monomer and 1 to 10 mole percent of at least one non-ionic comonomer. The copolymers are useful in inhibiting deposition of water hardness ions, in detergents and as dispersants in aqueous slurries. Copolymers are prepared by an aqueous solution polymerization process, comprising the steps of initially neutralizing at least 70%, on a molar basis, of the charge of a maleate monomer, followed by the slow addition of at least one polymerizable comonomer, together with an oxidative free radical initiator and a suitable metallic ion reductant, for synthesis over at least a three hour period at 80 to 100. degree. C. , followed by the addition of more initiator.

C11D 1318

US Classification:

510475

Abstract:

Water soluble polymers are prepared from an allyloxybenzenesulfonic acid monomer, a methallyl sulfonic acid monomer, a copolymerizable nonionic monomer, and a copolymerizable olefinically unsaturated carboxylic acid monomer. Aqueous compositions containing the water soluble polymers and nonionic surfactants are stable to phase separation of the polymer from the nonionic surfactant.

Abstract:

Water soluble polymers are prepared from an allyloxybenzenesulfonic acid monomer, a methallyl sulfonic acid monomer, a copolymerizable nonionic monomer, and a copolymerizable olefinically unsaturated carboxylic acid monomer. The polymers are used to disperse particulate matter and to inhibit the formation and deposition of mineral scale in aqueous systems and are used in detergent compositions.

International Classification:

C02F 512

US Classification:

210701

Abstract:

The water-treatment processes of this invention utilize maleate copolymers to sequester water hardness ions, modify crystal formation in water and inhibit scale formation (e. g. , in circulating water systems and oil field production systems), which polymers contain from about 40 to 70 mole percent of dicarboxylic functionality provided by a maleate monomer upon polymerization, from about 1 to about 15 mole percent of the polymerized residue of a non-ionic monomer, and from about 20 to about 50 mole percent of monocarboxylic functionality.

International Classification:

C02F 5/10
C08F 222/02
C08F 222/04

Abstract:

A method is described for selecting a treatment additive for aqueous systems, in which crystal habit modification properties are prioritized; for aqueously preparing a substantially poly-maleic additive through in-situ formation of maleic acid copolymer so that mono-carboxylic acids, non-ionic functional groups, and terminal hydroxyl groups are also formed during polymerization; and for applying such additives for treatment of aqueous systems. Treatment agents resulting from these processes are also described.
