I-Propionic Acid (CAS 79-09-4), i-carboxylic acid enemisebenzi eminingi esetshenziswa kabanzi ekulondolozweni kokudla kwezilwane, izithasiselo zokudla, izinto ezisetshenziswa emithini kanye nokuhlanganiswa kwamakhemikhali amahle, idonsela ukunaka okukhulu emakethe ngasekupheleni kukaSepthemba 2026, iqhutshwa yintuthuko yezobuchwepheshe basekhaya kanye nokukhula kwesidingo sesizini kuyo yonke imikhakha yezolimo yomhlaba wonke.

Ingqophamlando enkulu yezobuchwepheshe yafinyelelwa ngoSepthemba 16 yiSinochem Southwest Research Institute. Isitshalo sayo sokuhlola esingamathani ayi-100 ngonyaka se-methyl propionate nge-ethylene hydroesterification sasebenza ngokuqina isikhathi esingaphezu kwamahora angu-300 alandelanayo. Le nqubo iqophe ukuguqulwa kwe-carbon monoxide eyodwa okungaphezu kuka-99% kanye nokukhetha kwe-methyl propionate okungaphezu kuka-99.9%, okuphawula isinyathelo esibalulekile ekukhiqizweni okuluhlaza kwesizukulwane esisha kwamakhemikhali ochungechunge lwe-propionate kufaka phakathi okuphuma ku-propionic acid. Ngemuva kokuqinisekiswa okugcwele kwedatha yokuhlolwa, izinhlangano ezifanele zizoqhubekisela phambili ukwakhiwa kwezimboni. Le ndlela entsha kulindeleke ukuthi iguqule isimo sokuphakelwa kwesikhathi eside kwezinto ezihambisana ne-propionic acid ehlanzekile eShayina, isekela ukukhiqizwa kwamakhemikhali e-elekthronikhi amanzi, izinongo kanye nezinto zokwelapha.

Ngokwesisekelo semakethe, ikota yesi-4 yisikhathi sendabuko sokusetshenziswa okuphezulu kwe-propionic acid esezingeni lokuphakelayo. Abakhiqizi bemfuyo eNingizimu Melika, eNingizimu-mpumalanga ye-Asia nase-Afrika bathuthukisa ukuthengwa kwezithasiselo ezivimbela isikhunta ngaphambi kokugcinwa kokusanhlamvu kwasebusika. I-Propionic acid icindezela ngempumelelo ukukhiqizwa kwesikhunta kanye ne-mycotoxin ekudleni nasekudleni, okugcina inani lokudla okunomsoco futhi kunciphisa imfucuza yezinto ezingavuthiwe. Abakhiqizi bokudla emhlabeni wonke banciphisa izithasiselo zama-antibiotic, okuphakamisa kakhulu isidingo semakethe sezilondolozi ze-organic acid.

E-China, abakhiqizi be-propionic acid abavamile bagcina amazinga okusebenza azinzile. Ukuhlinzekwa kwe-Spot kulinganisela amazinga ezimboni, amazinga okudla kanye nama-oda e-feed. Imibuzo yokuthumela ngaphandle evela kumakhasimende ezolimo nokucubungula ukudla aphesheya ikhuphuke kakhulu kusukela maphakathi noSepthemba. Abathengi babonisa ukukhetha okunamandla kwe-propionic acid engu-99.5% ehlanzekile, enezinketho zokupakisha eziguquguqukayo kufaka phakathi ama-drum, ama-tote e-IBC kanye neziqukathi zamathangi e-ISO zezidingo ezahlukene zokuthunyelwa.

Noma kunjalo, abahlanganyeli bemakethe basabheka izici eziningana zengozi. Ukuguquguquka kwentengo yezinto ezingavuthiwe kungaletha ingcindezi yezindleko kubakhiqizi be-propionic acid. Ngaphandle kwalokho, ukuncintisana kwesifunda okuvela kubaphakeli baphesheya kuzoqhubeka nokuthinta izinzuzo zokuthumela kwamanye amazwe. Abahlaziyi bemboni bakhomba ukuthi imakethe ye-propionic acid yesikhathi esifushane izothola ukwesekwa okuvela ekudingweni kokudla kwesizini. Kodwa-ke ukwanda kwamanani okusobala akunakwenzeka ngaphandle kokunikezwa okwengeziwe okunciphile. Abathengi bomhlaba wonke baphakanyiswa ukuthi bahlele ama-oda kusenesikhathi ukuze babhekane nengcindezi yokuthunyelwa kwekota yesi-4. Ngokuhamba kwesikhathi, ubuchwepheshe bokukhiqiza obusha obuthuthukisiwe buzothuthukisa umkhawulo wokuncintisana waseShayina ekuhwebeni kwe-propionic derivatives yomhlaba wonke.
