Propionic Acid (CAS 79-09-4), asidi wogwiritsidwa ntchito kwambiri posunga chakudya cha ziweto, zowonjezera chakudya, mankhwala osakaniza ndi kupanga mankhwala abwino, amakopa chidwi cha anthu ambiri kumapeto kwa Seputembala 2026, chifukwa cha kupita patsogolo kwa ukadaulo wapakhomo komanso kukula kwa kufunikira kwa nyengo m'magawo azaulimi padziko lonse lapansi.

Chochitika chachikulu chaukadaulo chinakwaniritsidwa pa Seputembala 16 ndi Sinochem Southwest Research Institute. Chomera chake choyesera cha matani 100 pachaka cha methyl propionate kudzera mu ethylene hydroesterification chinagwira ntchito mosasunthika kwa maola opitilira 300 otsatizana. Njirayi idalemba kusintha kwa 99% ya carbon monoxide single-pass ndi kupitirira 99.9% methyl propionate selectivity, zomwe zikuwonetsa gawo lofunika kwambiri pakupanga zobiriwira za m'badwo watsopano wa mankhwala a propionate kuphatikiza zotumphukira za propionic acid. Pambuyo potsimikizira deta yonse yoyendetsedwa ndi oyendetsa, magulu oyenerera adzapititsa patsogolo ntchito yomanga mafakitale. Njira yatsopanoyi ikuyembekezeka kusintha mawonekedwe a nthawi yayitali a zinthu zoyera kwambiri za propionic acid ku China, kuthandizira kupanga mankhwala amagetsi, zonunkhira ndi mankhwala.

Ponena za maziko amsika, kotala lachinayi ndi nyengo yachikhalidwe yogwiritsira ntchito kwambiri propionic acid yopatsa thanzi. Opanga ziweto ku South America, Southeast Asia ndi Africa akuwonjezera kugula zowonjezera zoletsa nkhungu asanayambe kusungira tirigu m'nyengo yozizira. Propionic acid imaletsa bwino kuberekana kwa nkhungu ndi mycotoxin m'zakudya ndi silage, zomwe zimasunga thanzi la chakudya ndikuchepetsa zinyalala zosaphika. Opanga chakudya padziko lonse lapansi akuchepetsa zowonjezera zophera maantibayotiki, zomwe zikukweza kufunikira kwa msika kwa zosungira za organic acid.

Ku China, opanga ma propionic acid ambiri amakhala ndi mitengo yokhazikika yogwirira ntchito. Kupereka kwa zinthu zokhazikika kumayenderana ndi maoda a mafakitale, chakudya, komanso chakudya. Mafunso ochokera kunja ochokera kwa makasitomala akunja a ulimi ndi kukonza chakudya awonjezeka kwambiri kuyambira pakati pa Seputembala. Ogula akuwonetsa kukonda kwambiri ma propionic acid a 99.5% oyera kwambiri, okhala ndi njira zosinthira zomangira kuphatikizapo ng'oma, ma tote a IBC ndi zotengera za thanki za ISO pazofunikira zosiyanasiyana zotumizira.

Komabe, anthu omwe akutenga nawo mbali pamsika akuyang'anabe zinthu zingapo zoopsa. Kusinthasintha kwa mitengo ya zinthu zopangira kungayambitse kupsinjika kwa mtengo kwa opanga propionic acid. Kupatula apo, mpikisano wamadera kuchokera kwa ogulitsa akunja upitiliza kukhudza phindu la malonda ochokera kunja. Akatswiri amakampani akunena kuti msika wa propionic acid wa kanthawi kochepa udzalandira thandizo kuchokera ku kufunikira kwa chakudya cha nyengo. Komabe, kukwera kwamitengo kodziwikiratu sikungatheke popanda kupezeka kwina. Ogula padziko lonse lapansi akulangizidwa kuti akonze maoda pasadakhale kuti athane ndi kukakamizidwa kwa kutumiza kwa kotala lachinayi. Pamapeto pake, ukadaulo watsopano wopanga zinthu zobiriwira udzakweza mpikisano wa China mu malonda apadziko lonse lapansi a propionic acid.
