    • The present invention relates to a novel process for the manufacture of alkinediols of the formula I

      wherein ketones of the formula II

      are reacted with alkinols of the formula III

      in liquid ammonia in the presence of potassium hydroxide, wherein R 1 and R 3 are independently from each other a linear, branched or cyclic C 2-25 -carbon-hydrogen moiety, optionally containing 1 to 10 non-conjugated double-bond(s), and R 2 and R 4 are independently from each other linear C 1-4 -alkyl.
      The present invention also refers to the novel use of the alkindiols as emulgator, surfactant, dispersant, anti-foaming non-ionic agent, viscosity stabilizer, antistatic lubricant in the spinning of fibres, solvent, flavour, fragrance, wetting agent, sealing material or intermediate thereof and to the following novel alkindiols: 4,7-dihydroxy-2,4,7,9-tetramethyl-5-decine, 10, 13-dihydroxy-2,6,10,13,17,21-hexamethyl-11-docosine and 14, 17-dihydroxy-2,6,10,14,17,21,25,29-octamethyl-15-triacontine.
    • 本发明涉及一种用于制备式I的链烷醇的新方法,其中式II的酮在氢氧化钾存在下,在液氨中与式III的链醇反应,其中R 1和R 3独立地为 彼此是任选含有1-10个非共轭双键的直链,支链或环状的C 2-25-碳 - 氢部分,R 2和R 4彼此独立地为直链C 1-4 - 烷基。 本发明还涉及在纤维纺丝,溶剂,风味剂,香料,润湿剂,密封材料或纤维的纺丝中的烷二醇作为增效剂,表面活性剂,分散剂,消泡非离子剂,粘度稳定剂,抗静电润滑剂的新用途 中间体和下列新的烷二醇:4,7-二羟基-2,4,7,9-四甲基-5-癸胺,10,13-二羟基-2,6,10,13,17,21-六甲基-11 - 二肌苷和14,17-二羟基-2,6,10,14,17,21,25,29-八甲基-15-三烯酮。
