Document Type and Number:
Japanese Patent JP5207014
Kind Code:
B2
Abstract:
[Problem] To provide a device that can continuously refine an organic solvent, and can stably remove moisture from a large amount of organic solvent without generally requiring replacement of a dehydrating material. [Solution] An organic solvent dehydrating device dehydrates and removes moisture contained in an organic solvent to be treated by introducing the moisture-containing organic solvent to be treated so as to come in contact with a dehydrating material. The dehydrating material includes a cation exchange resin with a spherical shape. In the cation exchange resin of the dehydrating material, 90% or more particles have a diameter of 0.4 mm or less.
