| titleOfInvention | Method for synthesis of higher ethanolamines |
| abstract | FIELD: chemistry. n SUBSTANCE: claimed invention deals with improved method of obtaining diethanolamine and/or triethanolamine. Method consists in reaction of glycolaldehyde with monoethanolamine and/or diethanolamine with molar ratio of monoethanolamine and/or diethanolamine to glycolaldehyde in the range from 1:1 to 50:1 in presence of solvent and catalyst, containing nickel, cobalt and/or copper. Activated catalyst, obtained by reduction of catalyst precursor, which can contain oxygen-containing compound of Ni, Co and/or Cu, is used for the process. Reaction is usually carried out at temperature from 15 to 350°C and pressure from 10 to 350 bar. In the process of method realisation glycolaldehyde is brought in contact with activated catalyst. Activated catalyst during and after its reduction up to bringing in contact with glycolaldehyde is used under inert conditions. Activated catalyst possesses reduction degree of 30% or higher. It is desirable for activated catalyst, obtained by reduction of passivated catalyst, after reduction to have reduction degree which is at least by 2% higher than degree of reduction of reduced passivated catalyst. Monoethanolamine and/or diethanolamine, which were obtained by reaction of glycolaldehyde with ammonia and/or monoethanolamine, can be used for reaction. n EFFECT: method makes it possible to obtain products with high output and high selectivity. n 10 cl, 2 tbl, 13 ex |
