20150119578 | FILTRATION PROCESS FOR PURIFYING LIQUID AZOLE HETEROAROMATIC COMPOUND-CONTAINING MIXTURES - A process for removing impurities from a liquid azole heteroaromatic compound-containing (e.g., triazole-containing) mixture by: (a) providing a liquid azole heteroaromatic compound-containing mixture having impurities; and (b) passing the azole heteroaromatic compound-containing mixture through at least one filtration membrane which is a nanofiltration membrane and/or ultrafiltration membrane having a molecular pore size in the range of from about 200 daltons to about 1 kilodaltons to provide a permeate that is an at least partially purified azole heteroaromatic compound-containing mixture and a retentate with at least some impurities. | 04-30-2015 |
20140027675 | CORROSION INHIBITOR COMPOSITIONS COMPRISING TETRAHYDROBENZOTRIAZOLES SOLUBILIZED IN ACTIVATING SOLVENTS AND METHODS FOR USING SAME - A composition with one or more tetrahydrobenzotriazoles and one or more one or more tetrahydrobenzotriazole activating solvents, wherein the tetrahydrobenzotriazoles are solubilized in the activating solvents in an amount effective to inhibit corrosion of a metal or metal alloy which is corrodible in the presence of copper or copper corroding agents. Also, a method of using this composition to inhibit corrosion of a metal component which has a metal or metal alloy which is corrodible in the presence of copper or copper corroding agents. | 01-30-2014 |

Also, a method of using this composition to inhibit corrosion of a metal component which has a metal or metal alloy which is corrodible in the presence of copper or copper corroding agents. | 12-13-2012 |
20120308432 | CORROSION INHIBITOR COMPOSITIONS COMPRISING TETRAHYDROBENZOTRIAZOLES AND OTHER TRIAZOLES AND METHODS FOR USING SAME - A composition with a corrosion inhibitor component having one or more tetrahydrobenzotriazoles and one or more other triazoles; wherein the tetrahydrobenzotriazoles are in a weight ratio to the other triazoles such that the composition decreases the General Corrosion rate, as measured by copper electrodes in the presence of 10 ppm sodium hypochlorite, by at least about 0.05 mpy relative to a corrosion inhibitor component which is 100% of the other triazoles. Also, a method of using this composition to inhibit corrosion of a metal component which has a metal or metal alloy which is corrodible in the presence of copper or copper corroding agents. | 12-06-2012 |
20100022424 | USE OF TRIAZOLES IN REDUCING COBALT LEACHING FROM COBALT-CONTAINING METAL WORKING TOOLS - A method using one or more of certain triazoles in an amount effective to reduce cobalt leaching during a metal working process from a metal working tool comprising cobalt, such as tungsten carbide particles bonded by cobalt, wherein the one or more triazoles comprise at least butyl-benzotriazole, and optionally one or more other benzotriazoles. Also, a composition is provided which comprises a metal working fluid and one or more of these triazoles in an amount effective to reduce cobalt leaching from metal working tools comprising cobalt, such as tungsten carbide particles bonded by cobalt. | 01-28-2010 |
