Production method

1. Acetylene method "First, acetylene and formaldehyde are reacted at 98kPa and 80-95℃ in the presence of Cu-Bi catalyst to produce 1,4-butynediol. the latter is catalyzed by skeleton nickel and hydrogenated to 1,4-butenedioate at 1.372-2.06MPa and 50-60℃, followed by Ni-Cu-Mn/Al2O3 for further catalytic hydrogenation (13.7-20.6MPa), 120-140℃) into 1,4-butanediol, after removing the metal ions by ion exchange resin, it is purified by distillation to obtain pure product. 2. Maleic anhydride hydrogenation method. 3. Butadiene method. 1,3-butadiene, acetic acid and oxygen undergo acetylation reaction to produce 1,4-diacetoxy-2-butene, which is then hydrogenated, Made by hydrolysis. 4.1,4-Dichlorobutene method 1,4-Dichlorobutene is an intermediate product in the process of butadiene production of chloroprene. It is used as a raw material to obtain 1,4-butanediol through hydrolysis and hydrogenation.
