Panon ya uusaren so paraan na panaggawa na propionic acid manlapud byproduct na acetic acid?
Propionic Acid et inmuna ya ginawa diad panamegley na panag-ferment na asukar odino starch, odino diad pangibiig legan na woodization odino dry distillation. Balet, say panagpaalsa parad produksyon na propionic acid et sakey a mairap a dalan na metabolismo. Say produksyon na propionibacteria na propionic acid et naamper na saray end-product, kanian mairap so mantipon na atagey a konsentrasyon na produkto. Niarum ni, say pangibiig ed produkto et mairap, kanian saray paraan na panagpaalsa et agtanton makakompetensia no ikompara ed panagpaalagey na kemikal.
Say direktan oxidation na hydrocarbons et manunan paraan pian makagawa na acetic acid. Diad pangusar na light naphtha, liquefied petroleum gas, odino alkanes ya walay boiling points ya abeba ed sakey a temperatura bilang raw materials, tan manganese, cobalt, odino vanadium oxides bilang catalyst, say liquid-phase air oxidation et gagawaen ed 150-250°C tan 1.0-5.0 MPa pian makapawala na acetic acid, kaiba lay by-product Formic Acid tan propionic acid. Kada tonelada na light hydrocarbon, 0.65 tonelada na acetic acid, 0.06 tonelada na formic acid, tan 0.05 tonelada na propionic acid so nayarin nagawa. Sayan proseso et manguusar na agmabmabli iran raw materials tan simpli so workflow to, balet say komplikadon komposisyon na reaction mixture et mankaukolan na extractive distillation tan azeotropic distillation parad panagsian tan panaglinis, kanian atagey so gastos ed pinansyal.
