Resumo
A method for the quantification of small amounts (0.01–0.03 mol L–1) of ionic liquids (IL) [BMIM]Br, Bu4NBr, and Bu4NHSO4 in solutions using CHN analysis was proposed. The sample preparation procedure is based on evaporating the volatile components from the solution and concentrating of IL in an inert porous material (SiO2). Prior to preparation and analysis, the solid samples were heated at a temperature selected based on DTA data. This procedure can be used to determine the content of IL in solutions and catalytic mixtures.
