Non-aqueous solvent purification method and purification apparatus |
| abstract |
Kind Code: A1 A method for purifying a non-aqueous solvent using an ion-exchange resin having a reduced water content is provided in a simple and economical manner without requiring a variety of non-aqueous solvents for pretreatment. A pretreatment step of contacting the ion exchange resin with a pretreatment nonaqueous solvent having a dielectric constant of 15 or more at 25° C.; and a purification step of contacting the ion exchange resin after the pretreatment step with a non-aqueous solvent to be purified, wherein the pretreatment non-aqueous solvent and the non-aqueous solvent to be purified have a component matching rate of 85% by mass. A method for purifying a non-aqueous solvent characterized by the following. [Selection figure] None |
