He aha ngā painga o te n-Butane Oxidation Maleic Anhydride?
Te Whakahāoratanga n-Pūtāne Anhydride Maleic
Ka whakamahia e tēnei tukanga te n-butane (mai i te hau o te whare hanga hinu, te hau pakaru, te hau e pā ana ki te mara hinu rānei) hei rauemi mata. Ki te whakatauritea ki ngā tukanga tuku iho e ahu mai ana i te benzene, he pai ēnei:
He iti ake ngā utu mō ngā rauemi mata, he iti ake hoki te parahanga: 1.1–1.2 tana n-butane mō ia tana o te maleic anhydride (ki te whakataurite ki te 1.1–1.3 tana benzene mō te tukanga benzene).
Te hua ariā teitei ake: 1:1.69 (n-butane:anhydride maleic) vs. 1:1.256 (benzene:anhydride maleic).
Te whakaiti i te kai (nā te whanaketanga hangarau), te iti ake o te paitini (ki te benzene), me te iti ake o te pānga ki te taiao.
I te pikinga ake o te pēhanga taiao o te ao, he pai ake te pumau o te tukanga n-butane i te tukanga benzene—inaianei e neke atu ana i te 80% o te kaha o te ao, ā, kei te piki haere te whakamahinga.
