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 R1 and R3 are independently from each other a linear, branched or cyclic C2-25-carbon-hydrogen moiety, optionally containing 1 to 10 non-conjugated double-bond(s), and R2 and R4 are independently from each other linear C1-4-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造化学式I的炔二醇的新工艺,其中化学式II的酮与化学式III的炔醇在液氨中在存在氢氧化钾的情况下反应,其中R1和R3分别是线性、支链或环状的C2-25碳氢基团,可选地含有1至10个非共轭双键,而R2和R4则分别是线性的C1-4烷基。本发明还涉及炔二醇作为乳化剂、表面活性剂、分散剂、抗泡沫非离子剂、粘度稳定剂、防静电润滑剂在纤维纺丝中的新用途,溶剂、香精、香料、润湿剂、密封材料或其中间体,以及以下新型炔二醇:4,7-二羟基-2,4,7,9-四甲基-5-癸烯,10,13-二羟基-2,6,10,13,17,21-六甲基-11-二十二烷和14,17-二羟基-2,6,10,14,17,21,25,29-八甲基-15-三十烷。
