Cov txiaj ntsig ntawm n-Butane Oxidation Maleic Anhydride yog dab tsi?
Kev Oxidation ntawm n-Butane Maleic Anhydride
Cov txheej txheem no siv n-butane (los ntawm cov roj refinery, cov roj cracking, lossis cov roj cuam tshuam nrog cov roj hauv av) ua cov khoom siv raw. Piv rau cov txheej txheem benzene ib txwm muaj, nws muaj cov txiaj ntsig zoo:
Tus nqi khoom siv raw qis dua thiab muaj kuab paug tsawg dua: 1.1–1.2 t n-butane ib tuj ntawm maleic anhydride (vs. 1.1–1.3 t benzene rau cov txheej txheem benzene).
Qhov ntau dua theoretical yield: 1:1.69 (n-butane:maleic anhydride) vs. 1:1.256 (benzene:maleic anhydride).
Txo kev siv roj (nrog rau kev nce qib ntawm thev naus laus zis), txo qis kev lom (piv rau benzene), thiab txo qis kev cuam tshuam rau ib puag ncig.
Thaum lub ntiaj teb kev nyuaj siab ntawm ib puag ncig nce ntxiv, cov txheej txheem n-butane muaj kev ruaj khov dua li cov txheej txheem benzene - tam sim no suav txog ntau dua 80% ntawm lub peev xwm thoob ntiaj teb, nrog rau kev siv ntau zuj zus.
