Indlela yokukhiqiza i-propionic acid ukusuka emkhiqizweni we-acetic acid isetjenziswa njani?
I-Propionic Acid ekuthomeni yakhiqizwa ngokuvundiswa kwetjhukela nofana isitatshi, nofana ngokuhlukaniswa ngesikhathi sokukhiqiza iinkuni nofana ukuvundiswa komile. Kodwana, ukuvutshelwa kokukhiqiza i-propionic acid yindlela ebudisi yokugaya ukudla. Ukukhiqizwa kwe-propionibacteria kwe-propionic acid kuvinjelwa mikhiqizo yokugcina, okwenza kube budisi ukubuthelela amazinga aphezulu womkhiqizo. Phezu kwalokho, ukuhlukaniswa kwemikhiqizo kuyinselele, okwenza bona iindlela zokubilisa zingabi mncintiswano naziqathaniswa nokwenziwa kwamakhemikhali.
Ukutjhuguluka okuqondileko kwama-hydrocarbons yindlela ephambili yokukhiqiza i-acetic acid. Ukusebenzisa i-naphtha elula, i-petroleum gas, nofana ama-alkane anama-boil point angaphasi kwezinga elithileko lokutjhisa njengezinto ezisetjenziswako, kanye ne-manganese, i-cobalt, nofana i-vanadium oxides njenge-catalysts, ukukhiqiza umoya we-liquid-phase oxidation kwenziwa ku-150-250°C kanye ne-1.0-5.0 MPa ukukhiqiza i-acetic acid, kufaka hlangana ne-by-proct I-Formic Acid kanye ne-propionic acid. Ngethani ngalinye le-hydrocarbon elula, amathani ama-0.65 we-acetic acid, amathani ama-0.06 we-formic acid, kanye namathani ama-0.05 we-propionic acid angakhiqizwa. Ikambiso le isebenzisa izinto ezingabiziko begodu inokusebenza okulula, kodwana ukwakheka okuhlukahlukeneko komxube wokusabela kutlhoga ukuvundiswa okukhiphako nokuvundiswa kwe-azeotropic ukuhlukaniswa nokuhlanzwa, okurholela ekutheni kube neendleko eziphezulu zokutjala imali.
