Ngo ma obedo yoo me acetylene me yubu maleic anhydride ki i 1,4-butanediol?

yoo me Acetylene pi 1,4-Butanediol yubu maleic anhydride.

Mukwongo, acetylene rwate ki formaldehyde i kare ma tye ki Cu-Bi catalyst i 98kPa ki 80-95°C me kelo 1,4-butynediol. I ngeye, 1,4-butynediol ki loko i 1,4-butenediol i te tic pa skeletal nickel i 1.372-2.06MPa ki 50-60°C. Ma lubo, medo catalytic hydrogenation (13.7-20.6MPa, 120-140°C) ki tiimo ki Ni-Cu-Mn/Al2O3 me yubu 1,4-butanediol. Iyonge kwanyo ion me cuma ki ion exchange resin, 1,4-butanediol maleng ki nongo ki i distillation ki purification.

Pingo iyero Maleic Anhydride? En tye guti pa jami ma ki lwongo ni top-tier unsaturated polyester resins, ki en bene yabo jami ma pat pat ma tye piny (BDO, THF, ki mukene). Cwal kwena botwa kombedi me nongo yoo me MA ma ki yubu pi biyacara ni!
