Iindlela zokuThuthukiswa kwe-Maleic Anhydride
IV. I-Maleic Anhydride Imikhuba yokuThuthukiswa
E-China, i-benzene feedstock inengi ngokulawulwa kokuphakelwa okuguquguqukako, kanye nethekhnoloji yangekhaya ye-10,000-ton-scale ye-benzene oxidation-based Ukukhiqizwa kwe-Maleic anhydride uvuthiwe. Ngalokho, iinqophiso zentuthuko zamva nje zilandelako:
Ngakelinye ihlangothi, tjheja ukuthuthukisa nokuthuthukisa ikambiso ye-benzene oksijini ukwehlisa ukusetjenziswa nokusilaphazeka, ngaleyindlela kukhulise ukuncintisana.
Ngakelinye ihlangothi, khuphula imizamo ye-R&D yemikhiqizo ye-maleic anhydride. Ukwenza isibonelo, ukufunwa kwemikhiqizo efana ne-polybutylene terephthalate (PBT) (umkhiqizo we-1,4-butanediol, BDO) kanye ne-polytetramethylene ether glycol (PTMEG) (umkhiqizo we-tetrahydrofuran, THF) kuyakhula msinyana. Imakethe yangekhaya inesikhala esikhulu sokuphakelwa, begodu imikhiqizo le ithembele khulu ekuthengiseni ngaphandle.
