Yiziphi izindlela ezimbili zenqubo ye-anhydride yama-maleic?
Ukuqhathaniswa kwezindlela ezimbili zenqubo
Ubuchwepheshe bokukhiqiza be- I-Anhydride yamaMaleic ikakhulukazi kufaka phakathi ubuchwepheshe be-benzene oxidation kanye ne-n-butane oxidation ngokwemizila yezinto zokusetshenziswa. Ukuqhathaniswa kwe-benzene oxidation kanye ne-n-butane oxidation ngokwenqubo:
Ukugeleza kwenqubo: Lezi zindlela ezimbili zinokugeleza kwenqubo okufanayo; umehluko omkhulu usekusebenzeni.
Ukuvuthwa kobuchwepheshe: Zombili lezi zobuchwepheshe sezivuthiwe impela. Izikhungo zokukhiqiza zakwamanye amazwe zisebenzisa kakhulu indlela ye-n-butane, kuyilapho izikhungo zokukhiqiza zasekhaya zisebenzisa kakhulu indlela ye-benzene.
Indlela ye-n-butane njengomkhuba wokuthuthukiswa: Ngokombono wokuthuthukiswa kobuchwepheshe bangaphandle, imboni yomhlaba wonke ye-maleic anhydride isebenzisa kakhulu inqubo ye-n-butane. Ngakho-ke, isilinganiso samandla okukhiqiza asekelwe ku-n-butane siyaqhubeka nokukhula. Izinsizakusebenza ze-n-butane zakwamanye amazwe ziningi, futhi i-100% yezindawo zokukhiqiza ezisanda kwakhiwa zisebenzisa indlela ye-n-butane. Inqubo yokukhiqiza i-n-butane eYurophu ibambe u-89% wamandla okukhiqiza i-maleic anhydride yamanje, okokuqala iqedela ukuguqulwa komzila wezinto zokusetshenziswa. E-China, ngenxa yezinsizakusebenza eziningi ze-benzene ezivela emikhiqizweni yamakhemikhali amalahle, inqubo yokukhiqiza i-maleic anhydride esekelwe ku-benzene ibamba u-90% wamandla okukhiqiza i-maleic anhydride yezwe.
