Room temperature ionic liquids, as a new type of environmentally friendly “green solvents”, have many well-known and unique properties, which lay the foundation for their wide application in many fields. Two target products, 1-propyl-3-methylimidazolium taurine ionic liquid and 1- butyl ?3- methylimidazolium taurine ionic liquid, were synthesized by conventional two - step synthesis method. Hydrogen and carbon NMR spectra were also used to verify the chemical structure of the target products. Isothermal thermogravimetric analysis was used to record the decreasing trend of the weight for two ionic liquids samples over time. According to Langmuir equation and Clausius-Clapeyron equation, vaporization enthalpies of two ionic liquids were obtained. For the study of thermodynamic properties, the vaporization enthalpy data of ionic liquid in a certain temperature range are very important and indispensable.

The invention discloses a 1-methyl-3-propyl imidazole taurine ionic liquid as well as a preparation method and application thereof. The preparation method disclosed by the invention belongs to a two-step synthesis method and comprises the following steps: firstly carrying out pretreatment and prepurification on raw materials, then transforming 1-methyl-3-propyl imidazole chlorine salt into an oxyhydrogen type intermediate by virtue of anion exchange resin, and then mixing taurine with an oxyhydrogen type substance, so that a final product is obtained. The preparation method has the advantage that the prepared product has high purity. A byproduct in a reaction process is mainly water and can be removed by means of vacuum drying. The 1-methyl-3-propyl imidazole taurine ionic liquid product can be used for absorbing gas such as CO2 and SO2.
