丁炔二醇-1,4是重要的基本有机合成中间体。它可作为合成橡胶(丁二烯)、合成纤维(耐纶6,6)、塑料、溶剂、以及农药和药物的原料,同时由于它具有两个活泼的烃基和一个碳-碳三键,能进行多种反应,制成许多新品种。工业上丁炔二醇-1,4的合成是按照列普(Reppe)的方法进行的。乙炔在3—5大气压力下和甲醛水溶液借重金属的乙炔化合物如乙炔铜、乙炔汞、乙炔银等的催化作用,在100℃左右发生反应,得到丁炔二醇和少量丙炔醇。 Butynediol-1,4 is an important basic organic synthesis intermediates. It can be used as synthetic rubber (butadiene), synthetic fibers (nylon 6,6), plastics, solvents, and pesticides and pharmaceutical raw materials, and because it has two active hydrocarbon groups and a carbon-carbon triple bond, A variety of reactions, made of many new varieties. The synthesis of butynediol-1,4 is carried out according to the method of Reppe. Acetylene under 3-5 atmospheric pressure and formaldehyde aqueous solution by heavy metal acetylene compounds such as acetylene copper, acetylene mercury, silver acetylene catalyst, reaction occurs at about 100 ℃, to obtain a small amount of acetylene glycol and propargyl alcohol.
