Abstract
A method of preparing 2,5-bis(hydroxymethyl)tetrahydrofuran comprises heating a reaction mixture comprising 2,5-(hydroxymethyl)furaldehyde, an organic solvent, and a catalyst system comprising nickel and zirconium at a temperature, for a time, and at a pressure sufficient to promote reduction of the 2,5-(hydroxymethyl)furaldehyde to 2,5-bis(hydroxymethyl)tetrahydrofuran to produce a product mixture comprising 2,5-bis(hydroxymethyl)tetrahydrofuran.
Claims23
A method of preparing 2,5-furandialdehyde 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 said reaction mixture comprising 2,5-furandialdehyde;
- and
- ii) isolating 2,5-furandialdehyde from said reaction mixture.
