Synthesis and Liquefaction Properties of L-Alanine Hydrosulfate Ionic Liquid

Abstract:

Ionic liquid containing L-alanine cations and hydrogen sulfate was synthesized using L-alanine and sulfuric acid as materials. Fourier Transform Infrared Specctrometer was used to verify the final product. The results showed that the objective product was developed successfully. General properties of the final product were detected. The results showed that strong acidity, large viscosity, soluble in polar solvents and insoluble in nonpolar solvents were the product’s properties which were suitable for liquefying. The liquefaction rate of ionic liquid on paper was studied. Study the optimum liquefaction condition using the method of orthogonal experiment design. By stirring at 80°C for 3 hours using ionic liquid with the concentration of 100%, liquefaction rate of ionic liquid on paper was high.
