摘要

The compound of general formula (I), where R, R and R independently are selected from each other, is C 1 -C 6 alkyl and C 1 -C 5 hydroxyalkyl; R is independently selected from hydrogen, C-C-alkyl and C-C-hydroxyalkyl; R is independently selected from hydrogen, C-C-alkyl and C-C-hydroxyalkyl; m means 2, 3, 4 or 5; n means 2, 3, 4 or 5 and o means an integer of 0-10. The preferred compound of formula (I) is 2- (2-tert-butylaminoethoxy) ethylamine. Absorbents that contain a compound of formula (I) have the property of rapid absorption of carbon dioxide from fluid streams and are also suitable for the method of simultaneous removal of HS and CO, where the specified limit value HS is necessary, but complete removal of CO is not required.
