초록보기

A series of ionic liquids based on morpholinium cations were prepared. N-alkyl-N-methylmorpholiniumbromide , N- alky1-N-methylmorpholinium tetrafluoroborate, N- alky1-N-methylmorpholinium hexafluorophosphate and N-alky1-N-methylmorpholinium bis(trifluoromethanesulfonyl)imide were synthesized, and then thermal and electrochemical properties of prepared ionic liquids were measured. These morpholinium salts were found to be thermally stable near 673 K and electrochemically stable up to 6 V at room temperature. In conclusion, these new series of morpholinium based ILs might be potential candidates for electrolytes in batteries and other electrolytic devices.
