Acetic acid byproduct atanga propionic acid siam dan hi engtin nge an kalpui?
Propionic Acid hmanga siam a ni a tirah chuan sugar emaw starch emaw fermentation hmanga siam emaw, thing carbonization emaw dry distillation emaw laia inthen emaw hmanga siam a ni. Mahse, propionic acid siamna atana fermentation hi metabolic pathway harsa tak a ni. Propionic acid siam chhuahna propionibacteria hi end-product-in a tikhawlo a, hei vang hian product concentration sang tak khawlkhawm a harsa hle. Tin, product separation hi a harsa hle a, hei hian chemical synthesis nena khaikhin chuan fermentation methods te chu a inelna a ti tlem hle bawk.
Hydrocarbons direct oxidation hi acetic acid siamna atana hmanraw pawimawh ber a ni. Raw material atan light naphtha, liquefied petroleum gas, emaw alkanes temperature bituk aia hniam nei alkanes te hmangin, manganese, cobalt, emaw vanadium oxides te chu catalyst atan hmangin, liquid-phase air oxidation chu 150–250°C leh 1.0–5.0 MPa ah an ti a, acetic acid siam a ni a, by-product te pawh a tel Formic Acid hmanga siam a ni leh propionic acid te a ni. Light hydrocarbon ton khatah acetic acid ton 0.65, formic acid ton 0.06, leh propionic acid ton 0.05 siam chhuah theih a ni. Hetiang process hian raw material man tlawm tak tak a hmang a, workflow awlsam tak a nei a, mahse reaction mixture-a complex composition avang hian separation leh purification atan extractive distillation leh azeotropic distillation a ngai a, hei hian investment cost sang tak a thlen a ni.
