Non-protonic acid type acyl ammonium salt ionic liquid and preparation method therefor

The invention discloses non-protonic acid type acyl ammonium salt ionic liquid and a preparation method therefor and belongs to the technical field of novel chemical materials and preparation thereof. The ionic liquid is characterized in that a skeleton part of an acyl ammonium cation is or is close to a flat surface, and the structure facilitates the forming of low viscosity and high electric conductivity. At the temperature of 25 DEG C, the viscosity of the product is 21.6cP, and the electric conductivity reaches up to 14.46mS/cm. An alkylation reaction for preparing the acyl ammonium ionic liquid is characterized in that the reaction occurs in an oxygen atom of an amide group, N=O double bonds are changed into N-O single bonds, C-N is changed into C=N double bonds, and conjugate characteristics of the amide group are still reserved. In addition, the acyl ammonium ionic liquid is prepared from a cheap amide compound which serves as a raw material, the reaction conditions are mild, the operation is simple, a
