Propionic Acid (CAS 79-09-4), carboxylic acid iibelesyegwa kapati mukubamba chakulya chabanyama, zintu ziyungizyidwe muzyakulya, misamu iili akati-akati alimwi akupanga misamu mibotu, yakatola maanu kapati kumusika kumamanino aamwezi wa September 2026, akaambo kakuyaambele kwabusongo bwakupanga zintu alimwi akukomena kwabulimi munyika yoonse zibeela.

Chintu chipati chakachitwa mu September 16 a Sinochem Southwest Research Institute. Ibbazu lyakwe lyakusola lya 100-ton-a-mwaka lya methyl propionate kwiinda mukubelesya ethylene hydroesterification lyakabeleka kabotu kwamahola aatandila ku 300 aatobelana. Nzila eeyi yakalemba kwiinda 99% ya carbon monoxide yakusanduka kwachiindi chomwe antoomwe a 99.9% yakusala kwa methyl propionate, eezi zyakatondezya ntaamu mpati yakupanga misamu iikola ya propionate-series kubikkilizya a propionic acid derivatives. Musule akusinizyigwa koonse kwa data yabasikusunka, aabo beelede bayoosumpula kuyaka kwamakwebo. Eeyi nzila mpya ilalangilwa kuchincha nzila yakutola zintu zyaakati-akati zya propionic acid zisalala loko muChina, ikugwasyilizya kupanga misamu yamagesi, tununkilizyo azibelesyo zyamisamu.

Kuzintu zyantalisyo zyamusika, Q4 nceciindi cakubelesya kapati musamu wa propionic acid. Basikuvwuba banyama muSouth America, Southeast Asia antoomwe aAfulika bakayungizya kuula misamu iikwabilila nkumba kakutanaba kuyobola maila muchiindi chamupeyo. Asidi ya propionic ilakonzya kulesya buumba akuzyalana kwa mycotoxin muzyakulya azyakulya, eezyo zipa kuti zyakulya kazijisi busani akucesya tombe lyazintu zitabelesyegwi pe. Basikupanga zyakulya zyamunyika yoonse bali mukucheesya misamu iijaya tuzunda, mpawo eezi zipa kuti bantu bayanda misamu iikwabilila malwazi.

MuChina, basikupanga asidi ya propionic balazumanana kubeleka kabotu. Kusambala kwachiindi chifwiifwi kweendelanya maoda aamumakkampani, aazyakulya azyakulya. Mibuzyo yakutumizya zintu kunze aacisi kuzwa kuli basikuula bali kunze aacisi ibasambala zyakulya alimwi akubamba zyakulya yakatanta kapati kuzwa akati kamwezi wa September. Basikuula batondezya luyandisisyo lupati lwa 99.5% ya propionic acid iisalala, anzila zyakubikkila zintu zikonzya kuchincha mbuli ng'oma, IBC totes antoomwe a ISO tank containers muzintu zisiyene-siyene.

Nikuliboobo, aabo batola lubazu mumusika balalanga twaambo tunji tukonzya kuleta ntenda. Kuchincha kwamiulo yazintu zitabelesyegwi kulakonzya kuleta buyumuyumu bwakubelesya mali kuli basikupanga asidi ya propionic. Kunze lyaboobo, kuzundana kwamuchilawu kuzwa kuli basikusambala kunze kuyoozumanana kuchita kuti mpindu zyakusambala kunze. Basikuvwuntauzya mumakwebo batondezya kuti muulo wa propionic acid wachiindi chifwiifwi ulagwasigwa akuyanda chakulya chachiindi. Pesi kutanta kwamiulo takukonzeki pe kakunyina kujanika kusyoonto. Basikuula banyika yoonse balaambilwa kuti babambe maoda kakuchili chiindi kuchitila kuti bakonzye kulwana buyumuyumu bwakutumina zintu mu Q4. Muchiindi chilamfu, nzila zipya zyakupanga zintu zitakwe busani ziyoopa kuti China ibe aanguzu zyakuzundana mumakwebo aazwa ku propionic munyika yoonse.
