Lithium perfluoroalkylphosphonate was synthesized by LiF and perfluoroalkylphosphonate acid obtained by electrochemically fluorinating chlorodiisopropylphosphine. Some properties of a kind of electrolyte that was made from dissolving the lithium perfluoroalkylphosphonate in the mixed solvent with ethylene carbonate and dimethyl carbonate mass ratio 1∶1 were investigated, such as conductivity, stability toward hydrolysis and oxidative decomposition potential, and so on.

选取氯代二异丙基膦(C6H14PCl)为原料，利用电化学氟化方法，得到全氟烷基膦酸[(C3F7)2PF3]，(C3F7)2PF3与氟化锂反应得到全氟烷基膦酸锂Li[(C3F72PF4]，将其溶于碳酸乙烯酯和碳酸二甲酯质量比为1∶1的混合溶剂中得到电解液，考察电解液的电导率、抗水性及氧化分解电位。

Because of its nonpoisonous, DMC can substitute phosgene , dimethyl sulfate or methylating used as methyl pharmaceutical to improve the security of production and reduce the environmental pollution; As the solvent, DMC can substitute fluorine lyons , methyl chloroform , trichloroethylene , benzene , dimethylbenzene, etc.. And it can be used as the paint dope, clean solvent. As gasoline additive, DMC can raise hard octane value and oxygen content and improve its antiknock possibility.

由于DMC无毒，可替代剧毒的光气、硫酸二甲酯等作为甲基化剂或羰基化剂使用，提高生产操作的安全性，降低环境污染；作为溶剂，DMC可替代氟里昂、三氯乙烷、三氯乙烯、苯、二甲苯等用于油漆涂料、清洁溶剂等；作为汽油添加剂，DMC可提高其辛烷值和含氧量，进而提高其抗爆性。
