|Section2= |Section7= }} 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.〔Ignition Catalysts for Furfuryl Alcohol—Red Fuming Nitric Acid Bipropellant AIAA Journal Vol 8, No. 5 Pg 988.〕 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.〔(【引用サイトリンク】 title=Spectra-testen )〕〔http://copenhagensuborbitals.com/public/spectra.pdf The Spectra engine test report pdf〕 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. ==Uses == The major use of furfuryl alcohol is in the production of resins for bonding foundry sands for production of cores and molds. The binder system contains furfuryl alcohol in monomer or polymer form. It was also used for the first Lithium-ion batteries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Furfuryl alcohol」の詳細全文を読む スポンサード リンク
