Four reaction media have been assessed: two deep eutectic solvents (DES), choline chloride-oxalic acid (ChCl/ox) and choline chloride-urea (ChCl/urea), and two conventional ionic liquids, tetraethylammonium chloride (TEAC) and tetraethylammonium bromide (TEAB). Five acids (H2SO4, HCl, HNO3, H3PO4andp-toluensulfonic acid) have been evaluated in varying concentrations (5-30%) and time intervals (0-60 min), at different temperatures (100-140°C). Significant TRS production yields (as high as 83.7% in ChCl/ox for carnauba leaves) have been attained for both DES in combination with HNO3 10%, at 120°C for 30 min, with the additional advantage of low furfural and HMF by-products generation. info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 0.763 2016 MATERIALS SCIENCE, PAPER & WOOD 11 / 21 = 0.524 2016 Q3 T2 0.33 2016 Organic Chemistry 2016 Q3 Materials Chemistry 2016 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion López Sotelo, Juan Benito Correa Guimaraes, Adriana (orcid)0000-0003-2713-2786 Martín Ramos, Pablo Universidad de Zaragoza Hernández Navarro, Salvador Sánchez Báscones, Mercedes Navas Gracia, Luis Manuel Pérez Lebeña, Eduardo Martín Gil, Jesús 5011 500 Universidad de Zaragoza Dpto.
