Cobalt borate

Copper, Manganese, and Cobalt Borates. Borate salts of copper, manganese, and cobalt ate precipitated when borax is added to aqueous solutions of the metal(Il) sulfates or chlorides (152). However, these materials are no longer produced commercially.

Cyclooctane-l,5-diyl-bis(pyrazol-l-yl)borate (L) with cobalt(II), nickel(II), and zinc(II) nitrates gives [(j -L)M] (M = Co, Ni, Zn) strongly stabilized by the C—H M agostic interactions, which justifies their inclusion in the class of organometallic complexes [89AGE205, 91ICA(183)203, 92IC974]. 

The incorporation of anions from the electrolyte, such as borate and carbonate, into the oxide has also been shown to occur on iron and cobalt, such anions being restricted to the outer layers of the film. Attempts to find incorporation of chloride into passive iron surfaces from...

The organic solvent should feature a low solubility in water and a high dielectric constant. Numerous studies have been reported for liquid-liquid junctions involving DCE [43,62,70,71,73], nitrobenzene [67,68,74,75], and nitrophenyloctylether (NPOE) [56]. Various hydrophobic electrolytes have been employed in these solvents. Tetraphenylarsonium (TPAs+) [[71,75,76], bis-triphenylphosphoranylidene (BTPPA+) [43,50], and hydrophobic tetra-arylammonium [77,78] are among the cations used in the organic phase. The choice for anions has been mostly restricted to borate derivatives, tetraphenylborate (TPB ) [70,79,80], tetrakis(4-chlorophenyl)borate (TPBCH) [43,81,82], and tetrakis(penta-fluoro)phenylborate (TPFB ) [49,83], as well as dicarbollyl-cobaltate [75]. 

Cobalt(III)-alkylperoxo complexes find use in the oxidation of hydrocarbons.1342,1343 Since they release ROO and RO radicals upon mild heating in solution, they are effective oxidants under mild conditions, and produce catalytic systems in the presence of excess ROOH. Aliphatic C—11 bond oxidation by ConOOR (R = Con, alkyl, H) complexes including a hydrotris(pyrazolyl) borate ligand have also been reported, with homolysis of the peroxo O—O bond believed to be important in oxygenation of the C—H bond.1344...

A number of systems are being evaluated to reduce levels of cobalt in the complexes with resins. Organic borates and post vulcanisation stabilisers are being examined. Chlorotriazine-based bonding systems can reduce the adhesion system from three components to one.

Oxidation of Cyclododecane. 1,12-Cyclododecanedioic acid used in the production of polymers is synthesized in a two-step process864,866 similar to the manufacture of adipic acid. Cyclododecane is first oxidized to a mixture of cyclododecanol and cyclododecanone. Both the cobalt-catalyzed and the borate processes (Huels) are used. Further oxidation of the product mixture leads to 1,12-cyclododecanedioic acid. 

Some experiments were conducted with p-toluenesulfonic acid and acetyl borate as catalysts, using the same concentration range as for the metal acetates, to test their catalytic action in the reaction of acetaldehyde with peracetic acid. The results, although they did not rule out some catalytic activity, clearly indicated that these acids are much less active catalysts than manganese and cobalt acetates.
