５−ヒドロキシメチルフルフラール（ＨＭＦ）の水蒸気蒸留による反応溶液からの分離

摘要

A process for preparing solutions which comprise 5-hydroxymethylfurfural (HMF) and have reduced content of starting materials from the HMF synthesis or a reduced content of by-products of the HMF synthesis (called product solution hereinafter), characterized in that solutions comprising HMF starting materials or by-products of the HMF synthesis and an organic solvent having at least two ether groups (polyether for short) (called starting solution hereinafter) are treated with steam in an evaporator.
