Zochitika za Kukula kwa Maleic Anhydride
IV. Maleic Anhydride Zochitika Zachitukuko
Ku China, chakudya cha benzene chili ndi malamulo osinthasintha, ndipo ukadaulo wapakhomo wopanga benzene oxidation-based maleic anhydride wa matani 10,000 wakula. Chifukwa chake, njira zaposachedwa zopangidwira izi ndi izi:
Kumbali imodzi, yang'anani kwambiri pakukonza ndikusintha njira yothira benzene kuti muchepetse kugwiritsa ntchito ndi kuipitsa, potero muwonjezere mpikisano.
Kumbali inayi, onjezerani khama la kafukufuku ndi chitukuko pa zinthu za maleic anhydride. Mwachitsanzo, kufunikira kwa zinthu monga polybutylene terephthalate (PBT) (chopangidwa cha 1,4-butanediol, BDO) ndi polytetramethylene ether glycol (PTMEG) (chopangidwa cha tetrahydrofuran, THF) kukukulirakulira mofulumira. Msika wamkati uli ndi kusiyana kwakukulu kwa zinthu zomwe zimapezeka, ndipo zinthuzi zimadalira kwambiri zinthu zochokera kunja.
