Reaction Conditions:

with hydrogen at 180 - 200; under 60006 Torr; for 10 h;Product distribution / selectivity;Autoclave;Inert atmosphere;

Steps:

2
Example 2Preparation of 1,4-bis(hydroxyethyl)piperazine from diethanolamine (no solvent)Example 2 was carried out under the conditions of example 1 in the same apparatus. 100 g of diethanolamine (II) and 10 g of catalyst A were used. Gas chromatographic analysis (GC column: 30 m RTX Amin) indicated, at quantitative diethanolamine conversion, that the reaction output comprised 79% of 1,4-bis(hydroxyethyl)piperazine.
