I-Propionic Acid (CAS 79‐09‐4), i-carboxylic acid lehlukahlukene lesetjentiswa kakhulu ekugcineni kudla kwetilwane, tintfo letingetiwe ekudleni, tintfo letisemkhatsini temisebenti yemitsi kanye nekuhlanganiswa kwemakhemikhali lamahle, idvonsa kunaka lokukhulu kwemakethe ngasekupheleni kwenyanga yeNyoni nga 2026, lecondziswa sidzingo semhlaba wonkhe kanye nekukhula kwebuchwepheshe basekhaya. imikhakha yekulima.

Lizinga lelikhulu lebuchwepheshe lafezwa mhla tinge-16 Inyoni yiSikhungo Selucwaningo saseSinochem Southwest. Sitjalo sayo sekulinga se-methyl propionate ngekusebentisa emathani langu-100 ngemnyaka sasebenta ngendlela lecinile emahora langetulu kwa-300 lalandzelanako. Lenchubo yabhala ngetulu kwa 99% wekugucuka kwe carbon monoxide lokudlula kanye kanye ngetulu kwa 99.9% wekukhetsa kwe methyl propionate, lokuphawula sinyatselo lesibalulekile sekukhicita lokuluhlata kwesitukulwane lesisha semakhemikhali eluchungechunge lwe propionate kufaka ekhatsi tintfo letisuselwa ku propionic acid. Ngemuva kwekucinisekiswa ngalokuphelele kwemininingwane lesetjentiswa ngekulinga, emacembu lafanele atawuchubela embili kwakha ngesikali setimboni. Lendlela lensha ilindzeleke kutsi ibumbe kabusha indzawo yekuniketa sikhatsi lesidze yetintfo letisemkhatsini letihlobene ne-propionic acid lesetulu lehlantekile eChina, kusekela emakhemikhali e-elekthronikhi lamanti lasehla, tinongo kanye nekukhicita tintfo temitsi.

Kute tintfo letisisekelo temakethe, iQ4 sikhatsi sekusebentisa lesiphakeme sendzabuko se propionic acid yesigaba sekudla. Bakhiciti bemfuyo eNingizimu Melika, eSoutheast Asia nase Afrika bakhuphula kutfola tintfo letingetiwe letivimbela sikhunta ngaphambi kwekugcina tinhlavu tasebusika. iPropionic acid icindetela kahle sikhunta kanye nekukhicita kwe mycotoxin ekudleni nase silage, lokugcina umsoco wekudla futsi kunciphisa imfucuza yetintfo letiluhlata. Bakhiciti bekudla emhlabeni wonkhe banciphisa tintfo letingetiwe te antibiotic, lokuchubeka kuphakamisa sidzingo semakethe setintfo tekugcina esidi yetilwane.

EChina, bakhiciti labakhulu be-propionic acid bagcina emazinga ekusebenta lacinile. Kuphakelwa kwemabala kulinganisa ema-oda esigaba setimboni, esigabeni sekudla kanye nesigaba sekudla. Imibuto yekutfumela ngaphandle levela kumakhasimende langesheya kwetilwandle ekulima kanye nekucubungula kudla seyikhuphuke kakhulu kusukela emkhatsini waMandlovana. Batsengi bakhombisa kukhetsa lokucinile kwe‐propionic acid lesetulu lehlantekile 99.5%, ngetindlela tekupakisha letigucugucukako letifaka ekhatsi tigubhu, ema-totes e-IBC kanye netitja temathangi e-ISO tetidzingo letehlukene tekutfumela.

Noma kunjalo, bahlanganyeli bemakethe basabuka tintfo letinyenti letiyingoti. Kugucugucuka kwentsengo yetintfo letiluhlata kungaletsa kucindzeteleka kwetindleko kubakhiciti be propionic acid. Ngaphandle kwaloko, kuncintisana kwesifundza lokuvela kubaphakeli labaphesheya kwetilwandle kutawuchubeka nekutsintsa emazinga enzuzo yekutfumela ngaphandle. Bahlaziyi bemboni baveta kutsi imakethe yesikhatsi lesifishane ye propionic acid itawutfola kusekelwa kusuka ekufuneni kudla kwesikhatsi. Nobe kunjalo kukhula kwemanani lokusobala akunakwenteka ngaphandle kwekuniketa lokunyenti lokucinile. Batsengi bemhlaba wonkhe baphakanyiswa kutsi bahlele ema-oda kusengaphambili kute babhekane nekucindzeteleka kwekutfumela kwe-Q4. Ngesikhatsi lesidze, tebuchwepheshe lobusha bekukhicita lokuluhlata butawenta ncono umkhawulo wekuncintisana weChina ekuhwebeni kwemhlaba wonkhe kwetintfo letisuselwa ku-propionic.
