The main uses of 1,4-butynediol:

 

         Intermediates for butadiene synthesis, corrosion inhibitors, electroplating brighteners, polymerization catalysts, defoliants, chlorocarbon stabilizers. Butynediol can produce a series of important organic products such as butenediol, butanediol, n-butanol, dihydrofuran, tetrahydrofuran, γ-butyrolactone, pyrrolidone, etc., and can further manufacture synthetic plastics and synthetic fibers (nylon). -4), artificial leather, medicine, pesticides, solvents (N-methylpyrrolidone) and preservatives. Butynediol itself is a good solvent and is used as a brightener in the electroplating industry. Used in organic raw materials, solvents, cyanide-free plating solutions, also used in the artificial leather, pharmaceutical and pesticide industries.
