Acetic acid chuahmi chungin propionic acid chuah khawhnak lam cu zeitindah hman a si?
Propionic Acid a hramthawk ahcun changvut asiloah changvut cawhnak in, asiloah thing carbonization asiloah a ro cangmi thletnak lio ah tthennak in chuahmi a si. Sihmanhsehlaw, propionic acid chuah khawhnak caah cawhnuk cu a harmi thlennak lam a si. Propionibacteria nih propionic acid a chuahtermi cu a donghnak thilchuak nih a kham, cu nih cun thilchuak a tam tukmi khon a harter. Cun, thilri tthencheunak cu a har, cu nih cun chemical sernak he tahchunh tikah rawlchuannak lam kha zuamnak a tlawmter.
Hydrocarbons direct oxidation cu acetic acid chuah khawhnak ding caah a hrampi lam pakhat a si. A nemmi naphtha, liquefied petroleum gas, asiloah alkanes kha lumnak tlawmpal tang ah a lummi thilri ah hman in, le manganese, cobalt, asiloah vanadium oxides kha catalysts ah hman in, liquid-phase thli oxidation cu 150-250°C le 1.0-5.0 MPa ah acetic chuah khawhnak ding caah tuah a si, cu ah cun by-procts zong aa tel Formic Acid le propionic acid. A nemmi hydrocarbon ton khat ah, acetic acid ton 0.65, formic acid ton 0.06, le propionic acid ton 0.05 chuah khawh a si. Hi thil tuahnak nih hin a man a fawimi thilri a hman i riantuan ning a sawhsawh a ngei, asinain a harmi thilri cawhmi nih tthennak le thianhnak caah extractive distillation le azeotropic distillation a herhter, cu nih cun tangka hmannak man sang a chuahter.
