Title (EN) CORROSION INHIBITION
(FR) INHIBITION DE LA CORROSION
Abstract: front page image
(EN) A corrosion inhibiting compound with a general structure A-B or A-X-B for inhibition of corrosion of steel in acidic solution. A comprises a heterocyclic ring system having a plurality of cyclic Carbon atoms and at least one cyclic Nitrogen atom, wherein the at least one cyclic Nitrogen atom is neutral under neutral conditions and protonatable under acidic conditions. B comprises at least two unsaturated Carbon atoms. B may comprise a ring system or a polymerisable group.
(FR) L'invention concerne un composé inhibiteur de corrosion ayant une structure générale A-B ou A-X-B pour l'inhibition de la corrosion de l'acier en solution acide. A comporte un système hétérocyclique ayant une pluralité d'atomes de carbone cycliques et au moins un atome d'azote cyclique, ledit ou lesdits atomes d'azote cycliques étant neutres dans des conditions neutres et pouvant être protonés dans des conditions acides. B comporte au moins deux atomes de carbone insaturés. B peut comporter un système cyclique ou un groupe polymérisable.
