Filed:

Jan 18, 2001

Appl. No.:

10/181628

Inventors:

David M. Schubert - Los Angeles CA, US

Assignee:

U.S. Borax Inc. - Valencia CA

International Classification:

C01B035/18
C07F005/02
C09K021/00
A01N055/08

US Classification:

252601, 25238941, 423277, 501 964, 514 64, 564 8

Abstract:

A family of borate compounds containing an isolated (finite) nonaborate anion with the structural formula [BO(OH)]. Preferred amine nonaborate compounds have a resolved oxide formula of AO. 3BO. 2HO, where A is the monovalent cation of an amine salt, such as guanidinium and imidazolium. Also provided is a method for preparing these compounds by crystallization from an aqueous solution under mild conditions without the formation of significant amounts of by-products. These compounds have potential application as precursors for the production of advanced boron nitride ceramic materials, and as flame retardants, corrosion inhibitors, and biocides.

Appl. No.:

8/544903

Assignee:

U.S. Borax Inc. - Valencia CA

International Classification:

A01N 300
A01N 5914

US Classification:

427397

Abstract:

Lumber, plywood and other wood products are preserved from attack by fungi, termites and wood-destroying insects as well as fire and flame by treatment with a novel zirconium borate-containing preservative composition. The preservative can be formed by combination of a source of boron such as boric acid and the water-soluble salts thereof with a water-soluble zirconium salt. The ZrO. sub. 2 :B. sub. 2 O. sub. 3 weight ratio in the preservative composition is in the range of from about 0. 75:1 to about 10:1.

Inventors:

David M. Schubert - Los Angeles CA

Assignee:

U.S. Borax Inc. - Valencia CA

International Classification:

C01B 3512

US Classification:

423279

Abstract:

An improved method is provided for producing crystalline calcium hexaborate tetrahydrate, synthetic nobleite, by the reaction of boric acid and lime in an aqueous slurry. Reaction conditions include boric acid to water molar ratios of greater than 0. 25:1, lime to boric acid molar ratios in the range of 0. 05-0. 15:1 and temperatures in the range of 85. degree. -105. degree. C. A novel crystalline product is produced having a unique crystal habit resulting in improved physical properties. Dehydration of this product produced a novel amorphous, anhydrous product having similar crystal habit and physical properties.
