摘要：

Under the atmosphere of air and nitrogen, the thermal properties of 1-n-butyl-3-methylimidazolium bromide ionic liquid were studied with TGA-FTIR technique. Experimental results showed that the ionic liquid had certain vaporization pressure around its boiling point. This ionic liquid was mainly evaporated with increasing scanning temperature and no obvious decomposition was observed during the vaporization process. In the process of TGA, carbonization may occur. At the same time, oxidation may occur under the air atmosphere and the rates of carbonization and oxidation were nearly the same. In higher temperature, the carbonization and oxidation products were oxidized thoroughly.
