This invention is directed to a zwitterionic water-soluble imine of formula: (see above formula)] wherein R1 is heterocyclyl, heteroaryl, aryl, arylalkyl, cycloalkyl or lower alkyl; R2 is alkyl, alkenyl, aminoalkyl, diaminoalkyl, hydroxyalkyl, alkoxyalkyl, thioalkyl, alkylthioalkyl or arylalkyl; R3 is hydrogen and lower alkyl, or R1 and R3 taken together form a cycloalkyl; p is 2, 3, 4 or 5; and Z is CO2-, OCO2-, SO3-, OSO3-, PO3- or OPO3- which are useful as ferrous metal corrosion inhibitors.
La présente invention concerne une imine hydrosolublre zwitterionique de formule : (voir fomule ci-dessus) où R1 est un hétérocyclyle, un hétéroaryle, un aryle, un arylalkyle, un cycloalkyle ou un alkyle à chaîne courte; R2 est un alkyle, un alkényle, un aminoalkyle, un diaminoalkyle, un hydroxyalkyle, un alkoxyalkyle, un thioalkyle, un alkylthioalkyle ou un arylalkyle; R3 est un hydrogène et un alkyle à chaîne courte, ou R1 et R3 ensemble forment un cycloalkyle; p est égal à 2, 3, 4 ou 5; Z est un CO2-, OCO2-, SO3-, OSO3-, PO3- ou OPO3-s, qui sont d'efficaces inhibiteurs de la corrosion des métaux ferreux.
