|Section2= |Section7= }} 1,4-Butynediol is an organic compound that is an alkyne and a diol. It is a colourless, hygroscopic solid that is soluble in water and polar organic solvents. It is a commercially significant compound in its own right and as a precursor to other products. ==Synthesis== 1,4-Butynediol can be produced in the Reppe synthesis, where formaldehyde and acetylene are the reactants:〔Heinz Gräfje, Wolfgang Körnig, Hans-Martin Weitz, Wolfgang Reiß, Guido Steffan, Herbert Diehl, Horst Bosche, Kurt Schneider and Heinz Kieczka Butanediols, Butenediol, and Butynediol" in Ullmann's Encyclopedia of Industrial Chemistry, 2000, Wiley-VCH, Weinheim. 〕 :2 CH2O + HC≡CH → HOCH2CCCH2OH Several patented production methods use copper bismuth catalysts coated on an inert material. The normal temperature range for the reaction is 90 °C up to 150 °C, depending on the pressure used for the reaction which can range from 1 to 20 bar. 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「1,4-Butynediol」の詳細全文を読む スポンサード リンク
