Imikhuba Yokuthuthukiswa Kwe-Maleic Anhydride
IV. I-Anhydride yamaMaleic Izitayela Zokuthuthukiswa
E-China, i-benzene feedstock igcwele imithethonqubo yokuphakelwa eguquguqukayo, futhi ubuchwepheshe basekhaya bokukhiqizwa kwe-benzene oxidation-based maleic anhydride engamathani ayi-10,000 sebuvuthiwe. Ngakho-ke, iziqondiso zakamuva zentuthuko yilezi ezilandelayo:
Ngakolunye uhlangothi, gxila ekwenzeni ngcono nasekuthuthukiseni inqubo yokuxiliswa kwe-benzene ukuze kuncishiswe ukusetshenziswa kanye nokungcola, ngaleyo ndlela kuthuthukiswe ukuncintisana.
Ngakolunye uhlangothi, yandisa imizamo ye-R&D yemikhiqizo engezansi ye-anhydride yama-maleic. Isibonelo, isidingo semikhiqizo efana ne-polybutylene terephthalate (PBT) (umkhiqizo ongezansi we-1,4-butanediol, BDO) kanye ne-polytetramethylene ether glycol (PTMEG) (umkhiqizo ongezansi we-tetrahydrofuran, THF) sikhula ngokushesha. Imakethe yasekhaya inesikhala esikhulu sokunikezwa, futhi le mikhiqizo incike kakhulu ekungenisweni kwamanye amazwe.
