Synthesis a new family hybrid anionic/nonionic surfactant and investigation their physical properties in relation to chemical enhanced oil recovery.

ABSTRACT: This study details the synthesis of a new class family of surfactants with dual anionic and nonionic moieties (hybrid surfactants) based on maleic anhydride. The maleic anhydride reacted with 1-octene to prepare the corresponding 2-Octene-1-yl-Succinic Anhydride. Then, this anhydride was esterified with prepared ethoxylated alcohols (ethylene oxide = 20 units) having different alkyl chains to obtain nonionic moiety surfactants named as; NMAE-10, NMAE-12 and NMAE-14. The sulfonation was carried for the nonionic surfactant by using sodium bisulfite to get three anionic moiety surfactants (hybrid surfactants) designated as; AMAES-10, AMAES-12 and AMAES-14. FT-IR and ¹H NMR confirmed the surfactants' structures. At 50 °C, Alkane carbon number (ACN) and n_min were calculated by compar
