Yore mi yubu propionic acid kud i piny ma wok kud i acetic acid tiyu nenedi?

Propionic Acid juyike i acaki ni kadhu kud i nyayu sukari nyo starch, nyo ni poko kind yen i saa mi carbonization nyo dry distillation. Ento, fermentation pi yiku propionic acid ubedo yore mi tic ma tek. Propionibacteria timo pa propionic acid jukwero ku piny ma wok, ma weko bedo tek ni coko piny ma lee. Mi medo, poko piny ubedo lembe matek, ma weko yore mi timo fermentation doko yot ungo ka juporo ku chemical synthesis.
Oxidation direct pa hydrocarbons ubedo yore madit mi yubu acetic acid. Ni tiyo ku naphtha ma yot, liquefied petroleum gas, nyo alkanes ku kabedo mi lyethu ma piny pa temperature moko calu piny ma jutiyo kudu, man manganese, cobalt, nyo vanadium oxides calu catalysts, liquid-phase air oxidation jutimo i 150-250°C man 1.0-5.0 MPa pi niwodho acetic acid, ikinde ku by-procts Formic Acid man propionic acid. Pi ton acel pa light hydrocarbon, 0.65 tons pa acetic acid, 0.06 tons pa formic acid, man 0.05 tons pa propionic acid jucopo yubu. Lembe maeni tiyo ku piny ma wel pare yot man etiye ku tic ma yot, ento kit ma dul pa jam tic ma tung tung mitu kudu extractive distillation man azeotropic distillation pi poko man lwoko, ma kelo bey madwong.

Cwalu piny maber, jucwalo ikind nindu apar, dii kaneni pi nwangu wel ma piny pa Propanoic acid.
