20100099785 | TERTIARY AMINES BLOCKED WITH POLYMER ACIDS - Methods and compositions are provided for forming a catalyst. In one aspect, the catalyst is formed by mixing at least one tertiary amine with at least one polymer acid. Such catalysts are particularly useful in the polymerization of polyurethane foams. | 04-22-2010 |
20100130715 | REACTIVE AMINE CATALYSTS FOR POLYURETHANE FOAM - A process for the separation of a first amine having a tertiary amine group and a secondary amine group such as N,N,N′-trimethylbis(aminoethyl)ether from a di-tertiary amine such as N,N,N′,N′-tetramethylbis(aminoethyl)ether, comprising: contacting a mixture of the first amine and the di-tertiary amine with a carbonyl compound capable of forming an enamine such that the carbonyl compound reacts with the first amine to form an enamine; separating the enamine from the di-tertiary amine; and subsequently converting the enamine to the first amine. | 05-27-2010 |
20100144517 | SEPARATION OF N,N,N'-TRIMETHYLBISAMINO- ETHYLETHER FROM MIXTURES COMPRISING TERTIARY AMINES OR TERTIARY AMINOALKYLETHERS - The present invention relates to a method for recovering N,N,N′-trimethylbisaminoethylether from a mixture with its amide and a method for separating N,N,N′-trimethylbisaminoethylether from mixtures comprising tertiary amines or tertiary aminoalkylether as well as a composition comprising a mixture of N,N,N′-trimethylbisaminoethylether and a transamidation agent. | 06-10-2010 |
20100179297 | REACTIVE AMINE CATALYSTS FOR POLYURETHANE FOAM - Polyurethanes made using compounds of formula A: | 07-15-2010 |
20110009512 | REDUCTION OF ALDEHYDES IN AMINES - A tertiary amine, such as a tertiary amine catalyst that is useful in the production of polyurethanes, may undergo decomposition, which may result in the production of undesirable products. These tertiary amines, however, may be treated with a primary amine containing material to reduce the presence of the undesirable products to an acceptable level. Thus, a foam made from a treated tertiary amine will also have a reduction in the presence of the same undesirable products. | 01-13-2011 |
20110232489 | METHOD TO DECREASE DECOMPOSITION PRODUCTS IN SOLUTIONS THAT ABSORB ACIDIC GASES SUCH AS CARBON DIOXIDE AND THE LIKE IN THE PRESENCE OF OXYGEN - An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system. | 09-29-2011 |
20120071622 | Method for Providing a Secondary or Tertiary Amine - A method for providing a secondary or tertiary amine with formula (R | 03-22-2012 |
20120121810 | Release Compositions for Lignocellulosic Composites - Lignocellulosic composites are made by pressing a mixture of a particulate lignocellulosic material with polymeric MDI, in the presence of a fatty amine ethoxylate anti-masking agent. | 05-17-2012 |
20120269707 | USE OF 2-(3-AMINOPROPOXY)ETHAN-1-OL AS AN ABSORBENT TO REMOVE ACIDIC GASES - The present disclosure provides a scrubbing composition containing an aqueous solution of 2-(3-aminopropoxy)ethan-1-ol. The scrubbing composition is especially suited for use in removing acid gases, such as carbon dioxide and hydrogen sulfide, from gas streams. | 10-25-2012 |
20120271026 | INHIBITION OF AMINE OXIDATION - In an embodiment, an amine-oxidation inhibitor, such as a free radical scavenger and/or antioxidant, is added to an oxidation-sensitive amine, such as an amine catalyst, to inhibit oxidation of the amine. The inhibitor-treated amine may then be used in an application such as a polyurethane application to reduce the emission of undesired oxidation products from the polyurethane. | 10-25-2012 |
20130280155 | Sterically Hindered Amines and Associated Methods - Amine compositions comprising sterically hindered amines and associated methods are provided. In some embodiments, amine compositions of the present disclosure may be useful for selective removal of H | 10-24-2013 |
20140155655 | Method for providing a secondary or tertiary amine - A method for providing a secondary or tertiary amine with formula (R | 06-05-2014 |
