NOVEL POLYAMINES, SYNTHESIS PROCESS THEREOF AND USE OF SAME FOR THE SELECTIVE ELIMINATION OF H2S FROM A GASEOUS EFFLUENT COMPRISING CO2

The invention relates to novel polyamines of formula (I), derived from the reaction between a polyol diglycidyl ether and piperazine: n integer between 0 and 30, R1 of various forms, R2 of formula (g5), and R2 of formula (g6) when n=0; R6: H, C1-C6 alkyl or hydroxyalkyl radical, R7: C1-C6 alkyl or h...

Zusammenfassung:	The invention relates to novel polyamines of formula (I), derived from the reaction between a polyol diglycidyl ether and piperazine: n integer between 0 and 30, R1 of various forms, R2 of formula (g5), and R2 of formula (g6) when n=0; R6: H, C1-C6 alkyl or hydroxyalkyl radical, R7: C1-C6 alkyl or hydroxyalkyl radical, R6 and R7 possibly being joined to form a heterocycle containing 5, 6, 7 or 8 atoms when R6 is other than H, R8: H, C1-C4 alkyl or hydroxyalkyl radical. The invention also relates to the method for the preparation thereof, and the use of same in an absorbent solution based on amines for selectively eliminating H2S from a gaseous effluent containing H2S and CO2. L'invention porte sur de nouvelles polyamines de formule (I), issues de la réaction entre un diglycidyléther de polyol et de la pipérazine: n entier entre 0 et 30, R1 de différentes formes, R2 de formule (g5), et R2 de formule (g6) quand n=0; R6 : H, radical alkyle ou hydroxyalkyle en C1-C6, R7 : radical alkyle ou hydroxyalkyle en C1-C6, R6 et R7 pouvant être reliés pour former un hétérocycle à 5, 6, 7 ou 8 atomes lorsque R6 différent de H, R8 : H, radical alkyle ou hydroxyalkyle en C1-C4. L'invention concerne également leur méthode de préparation, et leur utilisation dans une solution absorbante à base d'amines pour éliminer sélectivement l'H2S d'un effluent gazeux contenant de l'H2S et du CO2.
