Ta yaya ake amfani da hanyar samar da propionic acid daga samfurin acetic acid?

Acid Propionic Da farko ana samar da shi ta hanyar fermentation na sukari ko sitaci, ko kuma ta hanyar rabuwa yayin fermentation na itace ko busasshen distillation. Duk da haka, fermentation don samar da propionic acid hanya ce mai wahala ta rayuwa. Ana hana samar da propionibacteria na propionic acid ta hanyar samfuran ƙarshe, wanda hakan ke sa ya yi wuya a tara yawan sinadarin. Bugu da ƙari, rabuwar samfura yana da ƙalubale, wanda hakan ke sa hanyoyin fermentation ba su da gasa idan aka kwatanta da haɗakar sinadarai.
Iskar gas ta hydrocarbons kai tsaye hanya ce ta farko ta samar da acetic acid. Ta amfani da naphtha mai sauƙi, iskar gas mai ruwa, ko alkanes masu tafasa a ƙasa da wani zafin jiki a matsayin kayan aiki, da kuma manganese, cobalt, ko vanadium oxides a matsayin masu haɓaka sinadarai, ana gudanar da iskar shaka ta iska a 150–250°C da 1.0–5.0 MPa don samar da acetic acid, tare da samfuran da suka haɗa da formic acid da propionic acid. Ana iya samar da kowace tan na hydrocarbon mai sauƙi, tan 0.65 na acetic acid, tan 0.06 na formic acid, da tan 0.05 na propionic acid. Wannan tsari yana amfani da kayan masarufi masu araha kuma yana da sauƙin aiki, amma hadaddun abubuwan da ke cikin cakuda amsawar suna buƙatar tacewa da tacewa azeotropic don rabuwa da tsarkakewa, wanda ke haifar da babban farashin saka hannun jari.

Isarwa mai dacewa, an aika cikin kwanaki 10, danna nan don samun rangwamen farashin Propanoic acid.
