| 20080197082 | Aminocarboxylic Acid Esters Having Eo/Po/Buo-Blockpolymers and Use Thereof as Demulsifiers - The present invention relates to aminocarboxylic esters with EO/PO/BuO block polymers, processes for preparing such compounds and the use of these compounds as emulsion breakers, in particular for crude oil emulsions. | 08-21-2008 |
| 20100016625 | METHOD FOR PRODUCING AMINONITRILES - The invention relates to a process for preparing an amino nitrile mixture comprising aminoacetonitrile (AAN) and from 5 to 70% by weight of iminodiacetonitrile (IDAN), which comprises heating crude AAN which is largely free of formaldehyde cyanohydrin (FACH-free) at a temperature of from 50 to 150° C. | 01-21-2010 |
| 20100029976 | METHOD FOR PRODUCING TETRAETHYLENEPENTAMINE - The invention relates to a process for preparing tetraethylenepentamine (TEPA) by hydrogenation of diethylenetriaminediacetonitrile (DETDN) over a catalyst. If appropriate, DETDN can also be present as a constituent of an amino nitrile mixture which additionally comprises diethylenetriaminemonoacetonitrile (DETMN). | 02-04-2010 |
| 20100029991 | METHOD FOR PRODUCING TRIETHYLENETETRAMINE - The invention relates to a process for preparing triethylenetetramine (TETA), which comprises hydrogenating ethylenediaminediacetonitrile (EDDN) in the presence of a catalyst and a solvent. | 02-04-2010 |
| 20100056828 | METHOD FOR PRODUCING ETHYLENEAMINES - The invention relates to a process for preparing an ethylene amine mixture, which comprises hydrogenating an amino nitrile mixture comprising at least 30% by weight of aminoacetonitrile (AAN) and at least 5% by weight of iminodiacetonitrile (IDAN) in the presence of a catalyst. Ethylenediamine (EDA) and/or diethylenetriamine (DETA) and, if appropriate, further ethylene amines can be isolated from the ethylene amine mixtures obtained. | 03-04-2010 |
| 20100094057 | METHOD FOR PRODUCING ETHYLENEDIAMINE - The invention relates to a process for preparing ethylenediamine by hydrogenation of aminoacetonitrile over a catalyst, wherein the hydrogenation is carried out in a solution comprising aminoacetonitrile, water in a proportion of from 0 to 60% by weight and a solvent and the aminoacetonitrile comprised in the solution is fed into the reaction vessel at a rate which is not greater than the rate at which the aminoacetonitrile reacts with hydrogen in the hydrogenation. | 04-15-2010 |
| 20100099872 | PRODUCTION METHOD FOR ETHYLENEAMINE MIXTURES - The invention relates to a process for preparing an ethylene amine mixture, which comprises hydrogenating an amino nitrile mixture comprising at least two α-amino nitriles in an amount of at least 5% by weight in each case in the presence of a catalyst and, if appropriate, a solvent. | 04-22-2010 |
| 20100121064 | NOVEL METHOD FOR PRODUCING TETA BY MEANS OF EDDN - The invention relates to a process for preparing triethylenetetramine (TETA), which, comprises the following steps:
