Room-temperature ionic liquid as well as preparation method and application thereof

The invention provides room-temperature ionic liquid as well as a preparation method and application thereof, and belongs to the technical field of new materials. The room-temperature ionic liquid provided by the invention is ionic liquid of carbon positive cations and is novel in structure, and the conductivity of the room-temperature ionic liquid is within the conductivity range (100-1000 [mu] S.cm <-1 >) of conventional room-temperature ionic liquid; meanwhile, an aprotic polar solvent which is low in cost and good in stability is adopted as an absorbent to absorb the halogen hydride-containing gas, and the ionic-like liquid which is high in additional value and is in a liquid state at the room temperature is prepared. The preparation method disclosed by the invention is simple, easy to realize industrial application and wide in application range, and solves the problems of simple use variety and complex preparation process of the room-temperature ionic liquid in the existing industrial ...
