Propionic Acid (CAS 79‐09‐4), carboxylic acid leyi tirhisiwaka ngopfu leyi tirhisiwaka ngopfu eka nhlayiso wa swakudya swa swifuwo, swiengeteri swa swakudya, switirhisiwa swa le xikarhi swa mirhi na ku endliwa ka tikhemikhali letinene, yi koka rinoko ro anama ra makete eku heleni ka September 2026, leswi hlohloteriwaka hi ku humelela ka thekinoloji ya laha kaya na ku kula ka xilaveko xa tinguva eka swiyenge swa vurimi swa misava hinkwayo.

Xiendlakalo lexikulu xa xithekiniki xi fikeleriwile hi ti 16 ta Ndzati hi Sinochem Southwest Research Institute. Feme ya yona yo ringeta ya 100‐ton‐hi lembe ya methyl propionate hi ku tirhisa ethylene hydroesterification yi tirhile hi ku tiya ku tlula 300 wa tiawara hi ku landzelelana. Endlelo ri rhekhodile ku tlula 99% wa ku hundzuriwa ka khaboni monokisayidi ya single‐pass na le henhla ka 99.9% wa ku hlawula ka methyl propionate, leswi fungha goza ra nkoka eka vuhumelerisi bya rihlaza ra xitukulwana lexintshwa eka tikhemikhali ta propionate‐series ku katsa na swikumiwa swa propionic acid. Endzhaku ka ku tiyisisiwa loku heleleke ka datha leyi fambisiwaka hi xikambelo, mavandla lama faneleke ya ta yisa emahlweni ku aka ka xikalo xa tiindasitiri. Ndlela leyi ya vutumbuluxi yi languteriwile ku vumba hi vuntshwa ndhawu ya mphakelo wa nkarhi wo leha wa switirhisiwa swa le xikarhi leswi fambelanaka na propionic acid ya vutengi bya le henhla eChina, ku seketela tikhemikhali ta elektroniki to tsakama ta le hansi, swinun’hweriso na vumaki bya switirhisiwa swa mirhi.

Eka masungulo ya makete, Q4 i nguva ya ndhavuko ya nhlohlorhi ya matirhiselo ya feed‐grade propionic acid. Vahumelerisi va swifuwo e South America, Southeast Asia nale Afrika va tlakusa ku xaviwa ka swiengeteri leswi sivelaka mould emahlweni ka vuhlayiselo bya mavele ya xixika. Propionic acid yi tshikelela kahle kutswariwa ka mould na mycotoxin eka swakudya na silage, leswi hlayisaka nkoka wa swakudya swa swakudya naswona swihunguta thyaka ra raw‐material. Vaendli va swakudya swa misava hinkwayo va hunguta swiengeteri swa antibiotic, leswi yaka emahlweni swi tlakusa xilaveko xa makete xa swihlayisi swa organic acid.

E China, vahumelerisi lavakulu va propionic acid va hlayisa swiyimo leswi tiyeke swa matirhelo. Mphakelo wa ndzhawu wu ringanisela tioda ta giredi ya indasitiri, giredi ya swakudya na giredi ya swakudya. Swivutiso swa ku rhumela ematikweni mambe ku suka eka tikhayente ta vurimi na vukorhokeri bya swakudya swa le matikweni ya le handle swi tlakukile ngopfungopfu ku sukela exikarhi ka Ndzati. Vaxavi va kombisa kutsakela lokukulu eka high‐purity 99.5% propionic acid, na tindlela to paka leti cinca cincaka kukatsa na swigubu, IBC totes na swibye swa mathangi ya ISO eka swilaveko swohambana hambana swa ku rhumeriwa.

Hambi swi ri tano, lava hlanganyelaka emakete va ha languta swilo swo hlayanyana leswi nga ni khombo. Ku cinca cinca ka nxavo wa raw‐material swinga tisa ntshikelelo wa ntsengo eka vahumelerisi va propionic acid. Handle ka sweswo, mphikizano wa miganga ku suka eka vaphakeri va le matikweni ya le handle wu ta ya emahlweni wu khumba swipimelo swa vuyelo bya ku xaviseriwa matiko mambe. Vakambisisi va indasitiri va kombisa leswaku makete wa nkarhi wo koma wa propionic acid wuta kuma nseketelo kusuka eka xilaveko xa swakudya swa tinguva. Hambi swi ri tano ku tlakuka loku nga erivaleni ka minxavo a ku nge endleki handle ka mphakelo lowu engetelekeke lowu tiyeke. Vaxavi va misava hinkwayo va ringanyetiwa ku lulamisa tioda ka ha ri emahlweni ku langutana na ntshikelelo wa ku rhumeriwa ka Q4. Hi nkarhi wo leha, thekinoloji leyintshwa leyi tumbuluxiweke ya vumaki bya rihlaza yi ta antswisa ku phikizana ka China eka mabindzu ya misava hinkwayo ya switirhisiwa leswi humaka eka propionic.
