Title:
非水電解液の製造装置および非水電解液の製造方法
Document Type and Number:
Japanese Patent JP7182427
Kind Code:
B2
Abstract:
To provide a device for producing a nonaqueous electrolytic solution, which is capable of easily performing purification while effectively suppressing an amino group of a weak-base anionic ion exchange group from being modified to a quaternary ammonium group, in performing purification where acidic impurities such as a hydrofluoric acid contained in a nonaqueous electrolytic solution such as an electrolytic solution for lithium ion batteries are adsorbed by a weak-base anionic ion exchange resin including an amino group.SOLUTION: A device for producing a nonaqueous electrolytic solution includes an ion exchange unit which accommodates a weak-base anionic ion exchange resin and which is for obtaining a nonaqueous electrolytic solution by passing therethrough an alkali metal salt electrolyte-containing solution which is alkali metal salt electrolytes dispersed in carbonic ester. The weak-base anionic ion exchange resin includes a weak-base anionic ion exchange group having one or more amino groups selected from a primary amino group and a secondary amino group.SELECTED DRAWING: Figure 1
