Alkanolamines of formula (I): R-NHCH2CH(OH)CH2CH3, or mixtures thereof wherein R is H, -CH2CH(OH)CH2CH3, an alkyl group having from 1 to 6 carbon atoms, an aryl group having from 6 to 12 carbon atoms, an aralkyl group having from 6 to 12 carbon atoms, or a cycloalkyl group having from 3 to 6 carbon atoms are effective in the removal of acidic gases from a fluid stream containing same and show superior degradation properties as compared to alkanolamines conventionally used in the gas purification applications.
Les alcanolamines correspondant à la formule (I): R-NHCH2CH(OH)CH2CH3, formule dans laquelle R représente un hydrogène, -NHCH2CH(OH)CH2CH3, un groupe alkyle portant de 1 à 6 atomes de carbone, un groupe aryle portant de 6 à 12 atomes de carbone, un groupe aralkyle portant de 6 à 12 atomes de carbone ou un groupe cycloalkyle portant de 3 à 6 atomes de carbone, se révèlent efficaces, s'agissant d'extraire des gaz acides d'un courant de fluide. Ces alcanolamines, de surcroît, se dégradent bien mieux que les alcanolamines habituellement utilisées lors de processus de purification de gaz.
