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.2016http://zaguan.unizar.es/record/64389http://zaguan.unizar.es/record/64389oai:zaguan.unizar.es:64389CELLULOSE CHEMISTRY AND TECHNOLOGY 50, 7-8 (2016), 761-770by-nchttp://creativecommons.org/licenses/by-nc/3.0/es/info:eu-repo/semantics/openAccess
