Abstract (en)

[origin: WO2018224350A1] The invention relates to novel polyamines of formula (I), derived from the reaction between piperazine and an epihalohydrin or a 1,3-dihalo-2-propanol, n being between 2 and 100, being indifferently an H or an alkyl radical comprising between 1 and 8 carbon atoms or a hydroxyalkyl radical corresponding to the following general formula (II): R2 being indifferently an H or an alkyl radical comprising between 1 and 6 carbon atoms, two R2 being able to be linked together by a covalent bond in order to form a ring if these are alkyl radicals. The invention also relates to the preparation method thereof, and the use thereof in an absorbent solution based on amines for selectively eliminating H2S from a gaseous effluent containing H2S and CO2.
