Yore mi acetylene pi 1,4-Butanediol yiko pa maleic anhydride.
Mir acel, acetylene timo tic ku formaldehyde i bedo pa Cu-Bi catalyst i 98kPa man 80-95°C mi wodhu 1,4-butynediol. I ngeye, 1,4-butynediol juyike i 1,4-butenediol i the catalysis pa skeletal nickel i 1.372-2.06MPa man 50-60°C. I ngeye, catalytic hydrogenation (13.7-20.6MPa, 120-140°C) jutimo ku Ni-Cu-Mn/Al2O3 mi yubu 1,4-butanediol. I ngei wodhu ion pa cuma nikadhu kud i ion exchange resin, 1,4-butanediol maleng ju nwango ku distillation man purification.
