(FR) TENSIOACTIFS POUR RÉCUPÉRATION AMÉLIORÉE D’HUILE
Abstract
(EN) The anionic cocogem surfactant of formula (I) for an oil production process of increased efficiency (I) wherein R1 and R2 is independently selected from hydrogen or C1-C18 straight or branched alkyl optionally substituted by OH; each R3 is independently selected from hydrogen; C1-C25 straight or branched alkyl or alkenyl optionally comprising inter-chain amido-group; aromatic group optionally substituted by C1-C25, preferably C5-C20, more preferably C5-C15 straight or branched alkyl, preferably selected from phenyl and diphenylether; or C10-C20 straight or branched alkenyl, alkadienyl or alkatrienyl; Z is C1-C18 straight or branched alkylene optionally substituted by one or two C1-C6 alkyl or preferably C3-C6 cycloalkyl, optionally comprising (EO)n and/ or (PO)m groups, wherein EO is ethylene-oxide i.e. -CH2CH2O-, and PO is propylene-oxide, i.e. -CH(CH3)CH2O-, wherein n and m is independently an integer of from 0 to 30 and n+m is an integer of from 1 to 30; and/or [NH(R4)]+ quaternary ammonium, wherein R4 is hydrogen, C1-C6 alkyl, preferably methyl or ethyl; R5 is hydrogen or C1-C6 alkyl, preferably methyl or ethyl; An is one or more groups selected from S03, CI or CO2; i is an integer of 0 or 1; p is an integer of 2 or 3; j is an integer of 2 or 3.
(FR) La présente invention concerne le tensioactif anionique gemini couplé à contre-ions (cocogem) de formule (I) pour un procédé de production d’huile d’une efficacité accrue (I) où R1 et R2 sont indépendamment sélectionnés parmi l’hydrogène ou un groupe alkyle linéaire ou ramifié en C1 à C18 éventuellement substitué par OH ; chaque R3 étant indépendamment sélectionné parmi l’hydrogène ; un groupe alkyle ou alcényle linéaire ou ramifié en C1 à C25 comprenant éventuellement un groupe amido inter-chaîne ; un groupe aromatique éventuellement substitué par un groupe alkyle linéaire ou ramifié en C1 à C25, préférablement en C5 à C20, plus préférablement en C5 à C15, préférablement sélectionné parmi le groupe phényle et diphényléther ; ou le groupe alcényle, alcadiényle ou alcatriényle linéaire ou ramifié en C10 à C20 ; Z est le groupe alcylène linéaire ou ramifié en C1 à C18 éventuellement substitué par un ou deux groupes alkyle en C1 à C6 ou préférablement cycloalkyle en C3 à C6, comprenant éventuellement les groupes (EO)n et/ou (PO)m, où EO est l’oxyde d’éthylène c’est-à-dire -CH2CH2O-, et PO est l’oxyde de propylène, c’est-à-dire -CH(CH3)CH2O-, où n et m sont indépendamment un nombre entier d’une valeur de 0 à 30 et n+m est un nombre entier d’une valeur de 1 à 30 ; et/ou [NH(R4)]+ le groupe ammonium quaternaire, où R4 est l’atome d’hydrogène, le groupe alkyle en C1 à C6, préférablement méthyle ou éthyle ; R5 est un atome d’hydrogène ou un groupe alkyle en C1 à C6, préférablement méthyle ou éthyle ; An est un ou plusieurs groupes sélectionnés parmi SO3, Cl ou CO2 ; i est un nombre entier d’une valeur de 0 ou 1 ; p est un nombre entier d’une valeur de 2 ou 3 ; j est un nombre entier d’une valeur de 2 ou 3.
