| Abstract: | A new ionic liquid with strong acid binuclear cations,namely,N,N'-alkyl-(3-methyl)-diimidazolium hydrogen sulfate,is used for the esterification of 1,7-pimelic acid and ethanol.The products and ionic liquids can be separated by simple methods.The esterification products could be easily separated in high yield from the reaction system via simple phase separation.The effects of the reaction conditions on the reaction results,such as the amount of catalyst,molar ratio of acid and alcohol,reaction time,etc,were... |
