Isebenza kanjani indlela yokukhiqiza i-propionic acid kusukela kumkhiqizo olandelanayo we-acetic acid?
I-Propionic Acid ekuqaleni kwakhiqizwa ngokubilisa ushukela noma isitashi, noma ngokuhlukaniswa ngesikhathi se-carbonization yezinkuni noma ukuhluzwa okomile. Kodwa-ke, ukubilisa ukukhiqizwa kwe-propionic acid kuyindlela eyinselele ye-metabolic. Ukukhiqizwa kwe-propionic acid ye-propionic acid kuvinjelwa yimikhiqizo yokugcina, okwenza kube nzima ukuqoqa amazinga aphezulu omkhiqizo. Ngaphezu kwalokho, ukuhlukaniswa komkhiqizo kuyinselele, okwenza izindlela zokubilisa zingancintisani kakhulu uma kuqhathaniswa nokuhlanganiswa kwamakhemikhali.
Ukushiswa ngqo kwama-hydrocarbon kuyindlela eyinhloko yokukhiqiza i-acetic acid. Kusetshenziswa i-naphtha elula, igesi kaphethiloli encibilikisiwe, noma ama-alkanes anamaphuzu abilayo ngaphansi kwezinga lokushisa elithile njengezinto zokusetshenziswa, kanye nama-manganese, i-cobalt, noma ama-vanadium oxides njengezinto ezibangela uketshezi, ukushiswa komoya wesigaba soketshezi kwenziwa ku-150–250°C kanye ne-1.0–5.0 MPa ukukhiqiza i-acetic acid, ngemikhiqizo elandelanayo efaka phakathi i-formic acid kanye ne-propionic acid. Ngethani le-hydrocarbon elula, amathani angu-0.65 e-acetic acid, amathani angu-0.06 e-formic acid, kanye namathani angu-0.05 e-propionic acid angakhiqizwa. Le nqubo isebenzisa izinto zokusetshenziswa ezingabizi futhi inohlelo lokusebenza olulula, kodwa ukwakheka okuyinkimbinkimbi kwengxube yokusabela kudinga ukushiswa kokukhipha kanye nokushiswa kwe-azeotropic ukuze kuhlukaniswe futhi kuhlanzwe, okuholela ezindleleni eziphezulu zokutshalwa kwezimali.
