AI Technical Summary
In the existing technology, the preparation of 5-hydroxymethylfurfural (HMF) has many side reactions and difficult separation, especially under high temperature and acid conditions, which makes it unstable and results in low product yield. The traditional aqueous phase reaction process has high energy consumption and complicated steps for product separation.
A mixed solvent system consisting of a polar aprotic solvent and a hydrophobic organic solvent is used to achieve automatic phase separation after homogeneous reaction through reaction-induced phase separation, and to enrich and separate products in situ while suppressing side reactions.
It improves the reaction selectivity and yield of HMF, simplifies the process flow, reduces energy consumption, and is suitable for industrial applications.
