Study On Applications Of Functional Ionic Liquids In Super Capacitor And Synthesis Of Azulenes

The main characteristics of Ionic liquids are non volatilization liquid, low melting point,wide electrochemical window, strong electrostatic field, good electrical and thermalconductivity, high thermal stability, choosing solubility and designability. Because of theionic liquid has many advantages, in recent years the study of ionic liquids is increasinglyactive, it was received widespread attention at home and abroad,1.This paper firstly summarized the ionic liquids has the important position of greenchemical and as sdlvent or catalyst in electrochemical and the organic synthesis research andapplication.2.In the electrochemical applications, containing alkoxy ring type structure and chainstructure of quaternary ammonium salt of the synthetic method were main discussed, and canserve as the super capacitor of organic electrolytes on the electrochemical properties weretested and discussed. Use the functional ionic liquid and acetonitrile solution of the supercapacitor electrolyte, and activated carbon electrode assembly into analog super capacitor,through the exchange impedance, circulation current-voltage and constant current chargingand discharging test means such as on the electrochemical properties have been studied. Theresults show that the organic electrolyte electrochemical window can achieve4V, highconductivity, can reach27.4mS／cm (1.5mol／L), and has good capacitance characteristics,reversible and cycling performance.3.In the application of fine organic synthesis, a kind of sulfonic acid synthesis typefunctional ionic liquid was main discussed, as solvent and catalyst, a series ofazuleno[2,1-b]pyridine derivatives, and construct the alkyl-substituted guaiazulenederivetives synthesis method, which has obtained a better effect.All the compounds were fully characterized and confirmed by elemental analysis, IR,MS,1H NMR spectral data.
