The ideal process conditions were found to be at a solvent-to-feed ratio of 0.008, 120 °C and 20 min with 1.0 g of oxidant, H2O2. Next generation environment-friendly solvents, low transition temperature mixtures (LTTMs) were synthesized from cactus malic acid with choline chloride (ChCl) and monosodium glutamate (MSG) as hydrogen bond acceptors (HBAs). The hydrogen-bonding interactions between the starting materials were determined. The efficiency of the LTTMs in removing lignin from oil palm biomass residues, empty fruit bunch (EFB) was also evaluated. The removal of amorphous hemicellulose and lignin after the pretreatment process resulted in an enhanced digestibility and thermal degradability of biomass. © 2017 Elsevier Ltd date: 2017 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85027836398&doi=10.1016%2fj.biortech.2017.08.043&partnerID=40&md5=314ede2a9a98d71ecbfb57fc7c166422 id_number: 10.1016/j.biortech.2017.08.043 full_text_status: none publication: Bioresource Technology volume: 244 pagerange: 941-948 refereed: TRUE issn: 09608524 citation: Yiin, C.L. and Quitain, A.T. and Yusup, S. and Uemura, Y. and Sasaki, M. and Kida, T.
