Xana ndlela yo humesa propionic acid kusuka eka byproduct ya acetic acid yi tirhisiwa njhani?
Asidi ya Propionic ekusunguleni ayi endliwa hiku virisa chukele kumbe starch, kumbe hiku hambanyisa hi nkarhi wa carbonization ya tihunyi kumbe dry distillation. Hambiswiritano, ku virisa kuva ku endliwa propionic acid i ndlela yo tika ya metabolic. Vuhumelerisi bya propionibacteria bya propionic acid byi siveriwa hi switirhisiwa swohetelela, leswi endlaka leswaku switika ku hlengeleta nhlayo yale henhla ya xiendliwa. Ku engetela kwalano, ku hambanyisa swihumelerisiwa swina ntlhontlho, leswi endlaka leswaku tindlela to virisa tinga phikizani ngopfu loko ti pimanyisiwa na ku endliwa ka ti khemikhali.
Ku oxidation hiku kongoma ka ti hydrocarbons i ndlela yosungula yo humelerisa acetic acid. Hiku tirhisa naphtha yo olova, gasi ya petroleum leyinga mati, kumbe ti alkanes letingana tindzhawu to vila ehansi ka mahiselo yokarhi tani hi switirhisiwa swoka swinga tirhisiwanga, na manganese, cobalt, kumbe vanadium oxides tani hi ti catalysts, liquid-phase air oxidation yi endliwa eka 150–250°C na 1.0–5.0 MPa kuva yi humelerisa acetic acid, laha swihumelerisiwa swikatsa Asidi ya Formic na asidi ya propioniki. Hi thani ya hayidirokhaboni yo vevuka, 0.65 wa tithani ta acetic acid, 0.06 wa tithani ta formic acid, na 0.05 wa tithani ta propionic acid swinga endliwa. Endlelo leri ritirhisa switirhisiwa swoka swinga durhi naswona rina maendlelo yo olova ya ntirho, kambe xivumbeko xo rharhangana xa nkatsakanyo wa reaction swilava extractive distillation na azeotropic distillation kuva swihambanisiwa naku basisiwa, leswi endlaka leswaku kuva na ntsengo wale henhla wa vuvekisi.
