Kedu ka esi arụ ọrụ usoro mmepụta propionic acid site na ihe si na acetic acid pụta?
Acid Propionic A na-emepụta ya na mbụ site na ịgba shuga ma ọ bụ starch, ma ọ bụ site na nkewa n'oge a na-agbaze osisi ma ọ bụ site na ịgbaze akọrọ. Agbanyeghị, ịgbaze maka mmepụta propionic acid bụ ụzọ metabolic siri ike. Ngwaahịa ikpeazụ na-egbochi mmepụta propionibacteria nke propionibacteria nke propionic acid, na-eme ka ọ sie ike ịchịkọta oke mkpokọta nke ngwaahịa ahụ. Na mgbakwunye, nkewa ngwaahịa siri ike, na-eme ka ụzọ ịgbaze ghara ịsọ mpi ma e jiri ya tụnyere mmepụta kemịkalụ.
Oxidation ozugbo nke hydrocarbons bụ ụzọ bụ isi e si emepụta acetic acid. Site na iji naphtha dị mfe, mmanụ ala a gwakọtara agwakọta, ma ọ bụ alkanes nwere ebe mmiri na-esi n'okpuru okpomọkụ ụfọdụ dị ka ihe ndị e ji emepụta ihe, na manganese, cobalt, ma ọ bụ vanadium oxides dị ka ihe na-eme ka ihe na-akpali akpali, a na-eme oxidation ikuku mmiri-phase na 150–250°C na 1.0–5.0 MPa iji mepụta acetic acid, yana ihe ndị sitere na ya gụnyere formic acid na propionic acid. Enwere ike ịmepụta kwa tọn hydrocarbon dị mfe, tọn 0.65 nke acetic acid, tọn 0.06 nke formic acid, na tọn 0.05 nke propionic acid. Usoro a na-eji ihe ndị dị ọnụ ala ma nwee usoro ọrụ dị mfe, mana ihe mejupụtara ngwakọta mmeghachi omume chọrọ mwepụta na azeotropic distillation maka nkewa na nhicha, na-ebute nnukwu ọnụ ahịa itinye ego.
