Organic solvent impurity removal material and organic solvent impurity removal method

A material for removing impurities from an organic solvent, which is a material for removing impurities from an organic solvent having a water content of 1,000 ppm or less, and which contains a porous ion exchange resin. The porous ion exchange resin preferably has one or more functional groups selected from the group consisting of a primary amino group, a secondary amino group, a tertiary amino group, and a quaternary amino group as an ion exchange group. A method for removing impurities from an organic solvent, in which an organic solvent having a water content of 1,000 ppm or less is brought into contact with a material for removing impurities from the organic solvent. 一种有机溶剂的不纯物除去材料，是用于自含水率1,000ppm以下的有机溶剂中除去不纯物的除去材料，包含多孔型的离子交换树脂。所述多孔型的离子交换树脂优选为具有选自由一级氨基、二级氨基、三级氨基、及四级铵基所组成的群组中的一个以上的官能基作为离子交换基。一种有机溶剂的不纯物除去方法，使含水率1,000ppm以下的有机溶剂与所述有机溶剂的不纯物除去材料接触。
