Description

（１）ジオールまたはトリオール含有溶液を、ポリアミドを含む機能層を有するナノ濾過膜に通じて濾過し、硫酸イオン濃度を９７．３％以上低減したジオールまたはトリオール含有溶液を透過側から回収する工程Ａを含む、ジオールまたはトリオールの製造方法。 (1) A step of filtering a diol or triol-containing solution through a nanofiltration membrane having a functional layer containing polyamide, and recovering from the permeate side a diol or triol-containing solution having a sulfate ion concentration reduced by 97.3% or more. A process for producing a diol or triol.
