Nzila zyakusumpuka kwa Maleic Anhydride
IV. Maleic Anhydride Nzila zyakusumpuka
MuChina, zintu zipangwa aa benzene zilivwulide loko mpawo kuli milawu iikonzya kuchincha, anzila zyakupanga zintu zili 10,000-ton-scale benzene oxidation-based Maleic anhydride Kupanga ulisimide. Aboobo, nzila zyakusumpula zyalino-lino zili boobu:
Kulubazu lomwe, bikkila maanu kukuchita obotu akusumpula nzila yakugwisya muya wa benzene kuchitila kuti kutabelesyegwi kabotu akusofwaazya, mpawo kuchitila kuti kube kuzundana.
Kulubazu lumwi, yungizya milimo ya R&D yazintu zizwa munsi-munsi zya maleic anhydride. Mbuli chitondeezyo, kuyandika kwazintu zilimbuli polybutylene terephthalate (PBT) (chintu chizwa ku 1,4-butanediol, BDO) antoomwe a polytetramethylene ether glycol (PTMEG) (chintu chizwa ku tetrahydrofuran, THF) chikomena chakufwambaana. Musika wamukati ulijisi lwiindano lupati lwazintu, alimwi zintu eezyi ziyeeme kapati azintu zizwa kunze aacisi.
