    • PURPOSE: A refining method for an methanide electrolyte is provided to easily and economically obtain the various organic methanide electrolyte having high purity to be used for a battery electrolyte, by manufacturing specific methanide having high purity and suitable for the electrolyte by refining it. CONSTITUTION: The methanide suitable for an electrolyte is expressed by the formula (x is one of integers from 1 through 8, M is H, Li, Na, KRb, Cs, Mg1/2, Ca1/2, Sr1/2 or Ba1/2). The manufacturing method for methanide electrolyte has a stage 1 to fractionally rectify free acid obtained by reacting the methanide expressed by the formula with concentrated sulfuric acid, a stage 2 to fractionally rectify the product expressed in the formula with H instead of M and obtained in the stage 1 by reacting it with phosphorous pentaoxide at a temperature of not less than its fusing point. The product from the stage 2 is taken into non-protic organic solvent, and is reacted with a metal such as Li and the like, their chlorides or hydrides, or if M is Li, it is reacted with alkyl-lithium, and a metal methanide corresponding to the formula is formed.
    • 目的:提供一种用于甲烷化电解质的精制方法,通过制备具有高纯度的特定甲烷化物并通过精制而适用于电解质,容易且经济地获得用于电池电解质的高纯度的各种有机甲烷化物电解质。 构成:适用于电解质的甲烷化由式(x为1至8的整数之一,M为H,Li,Na,KRb,Cs,Mg1 / 2,Ca1 / 2,Sr1 / 2或Ba1 / 2)。 甲烷化电解质的制造方法具有阶段1,对由式表示的甲烷化物与浓硫酸反应得到的游离酸进行分级整理,阶段2,将式(I)表示的产物用H代替M分级精馏,得到 在不低于其熔点的温度下使其与五氧化二磷反应。 将来自阶段2的产物置入非质子有机溶剂中,并与诸如Li等金属,它们的氯化物或氢化物反应,或者如果M是Li,则它与烷基锂反应,并且金属 形成对应于式的甲烷化物。
