Abstract

3-methyl-1-(4-sulfo-butyl)-benzimidazolium trifluoromethanesulfonate [BSMBIM][CF3SO3] as a new ionic liquid (IL) was synthesized and their structure was confirmed by NMR, FTIR and CHNS technique. The IL thermal stability is of the great significance for their applications. This IL thermal stability was investigated by TGA from 373.15-873.15 K with different heating rates (10, 15 and 20oC). The activation energy and pre-exponential factor were also evaluated using Kissinger (171.01 KJ/mol and 9.88×1012min-1), Ozawa (172.60 KJ/mol and 13.76×1012min-1) and Starink (171.30 KJ/mol and 10.50×1012min-1) methods, respectively.
