Preparation of 2,5-furandialdehyde from 2,5-(hydroxymethyl)furanaldehyde in the presence of 2,2,6,6-tetramethyl-i-piperidinyloxyl

摘要

A method of preparing 2,5-furandialdehye comprising:
i) reacting in a reaction mixture a material comprising 2,5-(hydroxymethyl)furaldehyde; 2,2,6,6-tetramethyl-1-piperidinyloxyl; and an organic oxidant under reaction conditions sufficient to convert 2,5-(hydroxymethyl)furaldehyde to 2,5-furandialdehyde, thereby producing a product comprising 2,5-furandialdehyde; and
ii) isolating 2,5-furandialdehyde from said product.
