Ino ninzila nzi ya acetylene yakubamba maleic anhydride kuzwa ku 1,4-butanediol?

Nzila ya Acetylene ya 1,4-Butanediol kulibambila kwa maleic anhydride.

Chakusanguna, acetylene ilasangana a formaldehyde kakuli Cu-Bi catalyst a 98kPa a 80-95°C kuti ipange 1,4-butynediol. Mpawo, 1,4-butynediol yakasandulwa kuba 1,4-butenediol aansi aakubelesya skeletal nickel a 1.372-2.06MPa a 50-60°C. Kuzwa waawo, kuyungizigwa kwa hydrogenation (13.7-20.6MPa, 120-140°C) kwakachitwa a Ni-Cu-Mn/Al2O3 kuti kube 1,4-butanediol. Musule akugwisya ma ion aabutale kwiinda mukubelesya ion exchange resin, 1,4-butanediol iisalala ilajanwa kwiinda mukusanzya akusalazya.

Nkaambo nzi ncosala Maleic Anhydride? Nchintu chipati loko cha polyester resins, mpawo chijalula makemikalu aasiyene-siyene (BDO, THF, azimwi). Kotutumina mulumbe lino kuti tubone nzila zya MA zibambidwe kabotu mumakwebo aako!
