We reacted maleic anhydride with 4-tert-butylbenzyl alcohol to form bis(4-(tert-butyl)benzyl) fumarate and sulfonated the produced diester. The esterification reaction was optimized for a maximum yield of 98 of bis(4-(tert-butyl)benzyl) fumarate. First-order reaction kinetics with respect to acid was observed. The activation energy was found to be 55.62 kJ/mol. The sulfonated product of diester was obtained by the sulfonation reaction and the yield of 82 of surfactant was achieved. The in-house developed surfactant effectively lowered down the IFT between CO2/brine to 4.2 mN/m. This surfactant is targeted for CO2-EOR applications. {\^A}{\copyright} 2014 Copyright Taylor \& Francis Group, LLC.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84899629457&doi=10.1080\%2f01932691.2013.803253&partnerID=40&md5=1dfc3cc74bf35495ba5ccd455449e3fb}, issn = {01932691}, keywords = {Activation energy; Enhanced recovery; Enzyme kinetics; Esterification; Maleic anhydride; Reaction kinetics; Surface active agents; Surface tension; Enzyme kinetics; Surface active agents, Diesters; Enhanced oil recovery; EOR; Esterification reactions; First order reactions; Fumarates, Carbon dioxide; Surface tension}, author = {Sagir, M. and Tan, I.
