NOUVEAUX AGENTS DE FLOCULATION ET DESEMULSIFIANTS

摘要

Polycationic compounds, utilisable as flocculation agents or as emulsion-breaking agents, which are obtained in branched form by reaction of compounds of the formula <IMAGE> in which R1 and R2 independently of one another denote alkyl(C1-5) or hydroxyalkyl(C2-5), Y denotes alkylene(C2-6), 2-hydroxy-1,3-propylene, -CH2CH2NHCONHCH2CH2- or -CH2CH2CH2NHCONHCH2CH2CH2-, A<(-)> denotes an anion, and x is 0 or an integer from 1 to 7, where when x is 2 or greater than 2, the individual meanings of Y are independent of one another, with polyfunctional amines.
