I-Propionic Acid (CAS 79‑09‑4), i-asidi ye-carboxylic eguquguqukayo esetyenziswa kakhulu ekugcineni ukutya kwezilwanyana, izongezo zokutya, izinto ezisetyenziswa ngamayeza kunye nokuhlanganiswa kweekhemikhali ezintle, itsala ingqalelo enkulu kwimarike ekupheleni kukaSeptemba 2026, iqhutywa kukuphumelela kwetekhnoloji yasekhaya kunye nokukhula kwemfuno yexesha lonyaka kumacandelo ezolimo ehlabathi.

Inqanaba elikhulu lobuchwephesha lifezekiswe nge-16 kaSeptemba yiSinochem Southwest Research Institute. Isityalo sayo sovavanyo seetoni ezili-100 ngonyaka se-methyl propionate nge-ethylene hydroesterification sisebenze ngokuzinzileyo kangangeeyure ezingaphezu kwama-300 ezilandelelanayo. Le nkqubo irekhode ukuguqulwa kwe-carbon monoxide nge-single pass engaphezulu kwe-99% kwaye ngaphezulu kwe-99.9% ye-methyl propionate selectivity, nto leyo ephawula inyathelo eliphambili kwimveliso eluhlaza yesizukulwana esitsha yeekhemikhali ze-propionate kuquka ne-propionic acid derivatives. Emva kokuqinisekiswa ngokupheleleyo kwedatha yovavanyo, amaqela afanelekileyo aya kuqhubela phambili ukwakhiwa kwemizi-mveliso. Le ndlela intsha kulindeleke ukuba itshintshe imeko yobonelelo lwexesha elide lwe-high-purity propionic acid enxulumene ne-intermediates eTshayina, ixhasa ukuveliswa kweekhemikhali ze-elektroniki ezimanzi, iziqholo kunye nezixhobo zamayeza.

Kwiziseko zemarike, ikota yesi-4 lixesha lesiqhelo lokusetyenziswa kwe-propionic acid ekumgangatho wokutya. Abavelisi bemfuyo eMzantsi Melika, eMzantsi-mpuma Asia naseAfrika banyusa ukuthengwa kwezongezo ezithintela ukungunda ngaphambi kokugcinwa kweenkozo zasebusika. I-Propionic acid ithintela ngempumelelo ukuveliswa kokungunda kunye ne-mycotoxin ekutyeni nasekutyeni, nto leyo egcina ixabiso lesondlo lokutya kwaye inciphisa inkunkuma yezinto eziluhlaza. Abavelisi bezondlo zehlabathi banciphisa izongezo zokubulala iintsholongwane, nto leyo ephakamisa ngakumbi imfuno yemarike yezigcini ze-organic acid.

ETshayina, abavelisi be-propionic acid abaphambili bagcina amazinga okusebenza azinzileyo. Ukunikezelwa kwemveliso kulinganisela ii-odolo zezinga lemizi-mveliso, izinga lokutya kunye nezinga lokutya. Imibuzo yokuthumela ngaphandle evela kubathengi bezolimo nabasebenza ngokutya kwamanye amazwe inyukile kakhulu ukususela phakathi kuSeptemba. Abathengi babonisa ukhetho olukhulu lwe-99.5% ye-propionic acid ecocekileyo kakhulu, kunye neendlela zokupakisha eziguquguqukayo kubandakanya iidrama, ii-totes ze-IBC kunye nezikhongozeli zeetanki ze-ISO kwiimfuno ezahlukeneyo zokuthunyelwa.

Nangona kunjalo, abathathi-nxaxheba kwimarike basajonga izinto ezininzi ezinobungozi. Ukuguquguquka kwamaxabiso ezinto eziluhlaza kunokubangela uxinzelelo lweendleko kubavelisi be-propionic acid. Ngaphandle koko, ukhuphiswano lwengingqi oluvela kubathengisi bamanye amazwe luya kuqhubeka nokuchaphazela imida yenzuzo yokuthumela ngaphandle. Abahlalutyi boshishino bathi imakethi ye-propionic acid yexesha elifutshane iya kufumana inkxaso kwimfuno yokutya kwexesha. Sekunjalo ukunyuka kwamaxabiso okucacileyo akunakwenzeka ngaphandle kokunikezelwa okuncinci. Abathengi behlabathi bacetyiswa ukuba balungiselele ii-odolo kwangaphambili ukuze bajongane noxinzelelo lokuthunyelwa kwe-Q4. Ekugqibeleni, ubuchwepheshe obutsha bokuvelisa obuluhlaza buya kuphucula umda wokhuphiswano lwaseTshayina kurhwebo lwehlabathi lwe-propionic oluvela kwimveliso.
