Acetylene mɔnu na 1, .4-Butanediol ƒe atike maleic anhydride ƒe dzadzraɖo.
Gbã la, acetylene wɔa dɔ kple formaldehyde le Cu-Bi ƒe nusi naa nu ʋãna ƒe anyinɔnɔ me le 98kPa kple 80-95°C me tsɔ wɔa 1,4-butynediol. Emegbe, wotsɔa hydrogen dea 1,4-butynediol me wòzua 1,4-butenediol le ƒumeŋuɖui ƒe nikel ƒe ʋuʋu te le 1.372-2.06MPa kple 50-60°C me. Eyome, wowɔa haidrodzin si naa nu ʋãna bubuwo (13.7-20.6MPa, 120-140°C) kple Ni-Cu-Mn/Al2O3 tsɔ wɔa 1,4-butanediol. Ne woɖe ga ions ɖa to ion exchange resin dzi vɔ la, wokpɔa 1,4-butanediol dzadzɛ to distillation kple eŋu kɔklɔ me.
