甲胺

Starting from the hydroxylamine (dimethyl amino ethanol, triethanolamine) and 1, 3-propane sultone, a series of hydroxyl and sulfonyl dual-functionalized zwitterionic salts were synthesized. Then dual-functionalized ionic liquids containing both hydroxyl and sulfonyl functional groups were produced successfully by zwitterionic salts and three kinds of strong acids (p-toluene sulfonic acid, trifluoromethanesulfonic acid, methanesulfonic acid) respectively. The structure of zwitterionic salts and dual-functional ionic liquids were confirmed by the 1H NMR and IR.
