Kodi njira yopangira propionic acid kuchokera ku zotsatira za acetic acid imagwira ntchito bwanji?
Propionic Acid Poyamba idapangidwa kudzera mu kuwiritsa shuga kapena wowuma, kapena mwa kulekanitsa panthawi ya carbonization ya nkhuni kapena kusungunuka kouma. Komabe, kuwiritsa kwa propionic acid ndi njira yovuta yogwiritsira ntchito kagayidwe kachakudya. Kupanga propionic acid ya propionic kumalepheretsedwa ndi zinthu zomaliza, zomwe zimapangitsa kuti zikhale zovuta kusonkhanitsa kuchuluka kwa mankhwalawo. Kuphatikiza apo, kulekanitsa mankhwala kumakhala kovuta, zomwe zimapangitsa kuti njira zowiritsa zikhale zochepa poyerekeza ndi kupanga mankhwala.
Kusungunuka mwachindunji kwa ma hydrocarbon ndi njira yayikulu yopangira acetic acid. Pogwiritsa ntchito naphtha yopepuka, mpweya wa petroleum wosungunuka, kapena ma alkanes okhala ndi kutentha kotsika ngati zinthu zopangira, ndi manganese, cobalt, kapena vanadium oxides ngati zoyambitsa, kusungunuka kwa mpweya wamadzimadzi kumachitika pa 150–250°C ndi 1.0–5.0 MPa kuti apange acetic acid, ndi zinthu zina kuphatikizapo formic acid ndi propionic acid. Pa tani imodzi ya hydrocarbon yopepuka, matani 0.65 a acetic acid, matani 0.06 a formic acid, ndi matani 0.05 a propionic acid amatha kupangidwa. Njirayi imagwiritsa ntchito zinthu zopangira zotsika mtengo ndipo ili ndi njira yosavuta yogwirira ntchito, koma kapangidwe kake kovuta ka reaction mix kamafuna kusungunuka kwa extractive ndi azeotropic distillation kuti ilekanitse ndi kuyeretsa, zomwe zimapangitsa kuti pakhale ndalama zambiri.
