Abstract: Organosulfonic acid functionalized montemorillonite-MMT (K10 and cloisite Na+) were prepared by different methodologies: (a) one-pot organosilylation or sulfonation, and (b) two-step organosilylation followed by sulfonation or oxidation. The physicochemical characterization ensured the success of the selected methodologies to promote HSO3-functionalization including high S contents (2.84 mmol S/g) and acidities up to 6.03 mmol H+/g (K10_PhSO3H).
