通过一锅法合成了一系列含磷酸二甲酯、甲基膦酸甲酯或甲基膦酸酯的烷基咪唑盐，作为室温离子液体，在温和条件下具有增溶纤维素的潜力。特别地，N-乙基-N ′-甲基咪唑鎓甲基膦酸盐能够通过在搅拌下将其保持在45 ℃下30分钟来制备10重量%的纤维素溶液，并且在没有预处理和加热的情况下使2-4重量%的纤维素可溶。
A series of alkylimidazolium salts containing dimethyl phosphate, methyl methylphosphonate, or methyl phosphonate prepared by a facile, one-pot procedure were obtained as room temperature ionic liquids, which have the potential to solubilize cellulose under mild conditions. Especially, N-ethyl-N'-methylimidazolium methylphosphonate enables the preparation of 10 wt% cellulose solution by keeping it at 45 degrees C for 30 min with stirring and rendered soluble 2-4 wt% cellulose without pretreatments and heating.
