Patent application number | Description | Published |
20080227632 | Advances in amination catalysis - Provided herein are catalysts useful in reductive amination, which include nickel, copper, zirconium and/or chromium, oxygen, and tin. The presence of the tin increases the selectivity of the catalyst in reductive aminations over the catalysts of the prior art. | 09-18-2008 |
20090198035 | POLYETHER POLYAMINE AGENTS AND MIXTURES THEREOF - Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation. | 08-06-2009 |
20100069672 | HIGH FUNCTIONALITY AMINE COMPOUNDS AND USES THEREFOR - In another exemplary embodiment, an amine functional curing agent has an Amine Hydrogen Functionality (AHF) of at least 7 and an Amine-Hydrogen Equivalent Weight (AHEW) of at least about 50. | 03-18-2010 |
20110009670 | CYCLOHEXANEDIMETHANAMINE BY DIRECT AMINATION OF CYCLOHEXANEDIMETHANOL - Embodiments of the present invention include methods for producing a cyclohexanedimethanamine by a reductive amination process. | 01-13-2011 |
20120184778 | HIGH FUNCTIONALITY AMINE COMPOUNDS AND USES THEREFOR - In another exemplary embodiment, an amine functional curing agent has an Amine Hydrogen Functionality (AHF) of at least 7 and an Amine-Hydrogen Equivalent Weight (AHEW) of at least about 50. | 07-19-2012 |
20120259075 | ETHERAMINES AND THEIR USE AS INTERMEDIATES FOR POLYMER SYNTHESIS - The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkoxylating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea. | 10-11-2012 |
20120283405 | ETHERAMINES CONTAINING FLEXIBLE AND RIGID SEGMENTS AND THEIR USE AS INTERMEDIATES FOR POLYMER SYNTHESIS - The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkyloxating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials. | 11-08-2012 |
20130165620 | ETHERAMINES CONTAINING FLEXIBLE AND RIGID SEGMENTS AND THEIR USE AS INTERMEDIATES FOR POLYMER SYNTHESIS - The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkyloxating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture.
