Furfuryl alcohol, also called 2-furylmethanol or 2-furancarbinol, is an organic compound containing a furan substituted with a hydroxymethyl group. It is a clear colorless liquid when pure, but becomes amber colored upon prolonged standing. It possesses a faint burning odor and a bitter taste. It is miscible with but unstable in water. It is soluble in common organic solvents. Upon treatment with acids, heat and/or catalysts, furfuryl alcohol can be made to polymerize into a resin, poly(furfuryl alcohol).

Furfuryl alcohol is manufactured industrially by the catalytic reduction of furfural which is obtained from corncob and sugar cane bagasse. It finds use as a solvent, but is primarily used as an ingredient in the manufacture of various chemical products such as foundry resins, adhesives, and wetting agents.

Furfuryl alcohol has been used in rocketry as a fuel which ignites hypergolically (immediately and energetically in contact) with white fuming nitric acid or red fuming nitric acid oxidizer.[2] The use of hypergolics avoids the need for an igniter. In fall of 2012, Spectra, a concept liquid rocket engine using white fuming nitric acid as the oxidizer to furfuryl alcohol fuel was static tested by Copenhagen Suborbitals.[3][4]

Furfuryl alcohol is probably a BK channel agonist.

Because of its low molecular weight, furfuryl alcohol can impregnate the cells of wood, where it can be polymerized and bonded with the wood by heat, radiation, and/or catalysts or additional reactants. The treated wood has improved moisture-dimensional stability, hardness, and decay and insect resistance; catalysts can include zinc chloride, citric or formic acid, or borates.[5][6]

Uses[edit]

The major use of furfuryl alcohol is in the production of resins for bonding foundry sands for production of cores and molds.[citation needed] The binder system contains furfuryl alcohol in monomer or polymer form.
