Title (EN) THIOL ADDUCTS FOR CORROSION INHIBITION
(FR) PRODUITS D'ADDITION THIOL DESTINÉS À L'INHIBITION DE LA CORROSION
Abstract:
(EN) Compounds, compositions and methods are provided for inhibiting corrosion at a surface in the production, transportation, storage, and separation of fluids such as crude oil and natural gas, the compounds having the formula (1) wherein: Each R1 is independently –CH2OH and –C(O)OH; R2 is (AA) or (BB); Each R3 is independently hydrogen or R5, or both R3 together form a ring via a linker (CC); Each R4 is independently hydrogen or R5; R5 is –CH2SC2H4R1; and n is an integer from 0 to 3.
(FR) L'invention concerne des composés, des compositions et des procédés destinés à inhiber la corrosion au niveau d'une surface dans la production, le transport, le stockage et la séparation de fluides tels que l'huile brute et le gaz naturel, les composés possédant la formule (1) dans laquelle : chaque R1 est indépendamment –CH2OH et –C(O)OH ; R2 est (AA) ou (BB) ; chaque R3 est indépendamment un atome d'hydrogène ou R5, ou les deux R3 forment ensemble un cycle par l'intermédiaire d'un lieur (CC) ; chaque R4 est indépendamment un atome d'hydrogène ou un R5 ; R5 est –CH2SC2H4R1 ; et n est un nombre entier de 0 à 3.
