Msika wa formic acid ndi wokulirapo kwambiri ndipo pakadali pano umadziwika ndi kafukufuku wopitilira pa ntchito zatsopano zomwe zikuyembekezeka kuthandiza makampaniwa kukula mofulumira kwambiri pakati pa 2021-2027.
Malinga ndi lipoti la World Health Organization, kudya chakudya mosasamala ndiko kwachititsa kuti anthu 600 miliyoni azidwala matenda obwera chifukwa cha chakudya komanso anthu pafupifupi 420,000 amwalire padziko lonse lapansi. Kuphatikiza apo, matenda 1.35 miliyoni omwe atchulidwa ndi CDC mwina adayambitsidwa ndi Salmonella, zomwe zidapangitsa kuti anthu pafupifupi 26,500 agonekedwe m'chipatala ndi anthu 420 amwalire ku United States.
Poganizira kuchuluka kwa tizilombo toyambitsa matenda tomwe timapezeka m'zakudya komanso momwe tizilombo toyambitsa matendati timakhudzira kwambiri, kugwiritsa ntchito njira zochepetsera kupezeka kwa mabakiteriya m'zinyama ndi njira yabwino yothetsera vutoli. Pachifukwa ichi, kugwiritsa ntchito ma organic acid mu chakudya cha ziweto kungathandize kwambiri poletsa mabakiteriya ndikuletsa kuti asafalikirenso mtsogolo. Apa ndi pomwe formic acid imagwira ntchito.
Formic acid imaletsa tizilombo toyambitsa matenda m'zakudya za ziweto ndipo imaletsa kukula kwawo m'mimba mwa mbalame. Kuphatikiza apo, mankhwalawa afotokozedwa kuti ndi mankhwala othandiza kwambiri polimbana ndi mabakiteriya a Salmonella ndi tizilombo tina.
Kafukufuku wofunikira angathandize makampani opanga formic acid pakugwiritsa ntchito chakudya cha ziweto
Mu Epulo 2021, kafukufuku adawonetsa kuti sodium-buffered formic acid ingagwiritsidwe ntchito podyetsa nkhumba ndi mashed m'malo odyetsera nkhumba, alimi a nkhuku, ndi omalizitsa nkhumba kuti apereke miyezi itatu ya acidification yopitilira.
Kuchuluka kwa mankhwalawa kunasonyeza kukhazikika kwakukulu m'zakudya zophikidwa ndi zophikidwa, ndipo kuphatikizidwa pamlingo wapamwamba kunachepetsa pH ya chakudya. Zotsatirazi zingathandize opanga kumvetsetsa bwino kugwiritsa ntchito formic acid muzakudya zophikidwa ndi zophikidwa pazakudya za ziweto.
Ponena za izi, ndikofunikira kutchula za Amasil formic acid ya BASF. Malinga ndi kampaniyo, mankhwalawa amathandizira kupanga bwino nyama mwa kukonza ukhondo wa chakudya, zomwe zingathandize opanga mazira ndi nkhuku kupereka zokolola zabwino.
Ngakhale kuti chakudya cha ziweto chikugwiritsidwa ntchito kwambiri m'makampani onse, formic acid ikugwiranso ntchito m'mafakitale ena - ena mwa iwo ndi mafakitale opanga mankhwala, zikopa, nsalu, rabara ndi mapepala.
Malinga ndi kafukufuku waposachedwa, 85% formic acid imaonedwa kuti ndi yotetezeka, yotsika mtengo, komanso njira ina yothandiza pochiza ziphuphu zofala ndi zotsatirapo zochepa.
Komabe, kuwonjezeka kwa matenda a ziphuphu padziko lonse lapansi kudzakhudza kwambiri kugwiritsa ntchito formic acid m'mankhwala pochiza matenda awa. Matenda a ziphuphu amakhudza pafupifupi 10 peresenti ya anthu padziko lonse lapansi, ndipo kufalikira kwa ana azaka zoyambira sukulu kuli pafupifupi 10 mpaka 20 peresenti, malinga ndi lipoti laposachedwa la 2022 la National Center for Biotechnology Information. Amapezeka kwambiri mwa opanga nyama ndi odwala omwe ali ndi chitetezo chamthupi chofooka.
Mu gawo la nsalu, formic acid nthawi zambiri imagwiritsidwa ntchito kuchotsa mpweya wa nitrous acid, utoto wopanda mbali ndi utoto wofooka wa asidi mu njira ya Tyco's sub-micron sodium nitrate. Chosakaniza ichi chimadziwika kuti chimathandizira kuchuluka kwa utoto mu njira za chromium mordant. Kuphatikiza apo, kugwiritsa ntchito formic acid m'malo mwa sulfuric acid pakuyika utoto kumatha kupewa kuwonongeka kwa cellulose, chifukwa acidity ndi yocheperako, ndi wothandizira wabwino.
Mu makampani opanga rabara, formic acid ndi yabwino kwambiri pophatikiza latex yachilengedwe chifukwa cha zabwino zake zambiri, kuphatikizapo:
Ubwino uwu umapangitsa kuti phula ili likhale limodzi mwa zinthu zabwino kwambiri zopangira mphira wouma. Kafukufuku wasonyeza kuti kukhuthala kwa mphira wachilengedwe pogwiritsa ntchito kuchuluka koyenera kwa formic acid ndi njira yomwe ikulangizidwa kungapangitse mphira wouma wabwino kukhala ndi mtundu wabwino womwe opanga ndi ogulitsa amafunikira.
Kuwonjezeka kwa kufunika kwa latex ya rabara kuti iwonjezere kupanga magolovesi, zipewa zosambira, chingamu ndi zinthu zina kungakhudze malonda apadziko lonse lapansi a formic acid compound. Komanso, kukula kwa malonda a magolovesi panthawi ya mliri wa COVID-19 kwapereka chiwonjezeko chabwino pamsika wa formic acid.
Kuchuluka kwa mpweya woipa wa carbon dioxide padziko lonse lapansi kukuwonjezeka, ndipo kupanga mankhwala osiyanasiyana kudzangowonjezera kuchuluka kwa mpweya wa carbon. Malinga ndi lipoti la IEA, mpweya woipa wa carbon wochokera ku kupanga mankhwala oyamba unapanga 920 Mt CO2 mu 2020. Pachifukwa ichi, maboma ndi mabungwe tsopano akugwira ntchito yochepetsa mpweya woipa wa carbon posintha mpweya kukhala ma organic acid omwe angagwiritsidwe ntchito m'mafakitale osiyanasiyana.
Mu chitsanzo chimodzi chotere, gulu lofufuza ku Tokyo Institute of Technology ku Japan linapanga njira yopangira kuwala kwa dzuwa yomwe ingachepetse mpweya wa carbon dioxide pogwiritsa ntchito kuwala kwa dzuwa ndikusandutsa asidi wa formic wokhala ndi kusankha kwa pafupifupi 90 peresenti. Zotsatira zake zinasonyeza kuti njirayo inatha kuwonetsa kusankha kwa asidi wa formic ndi 4.3% ndi kuchuluka kwa quantum.
Ngakhale kupanga formic acid kuchokera ku carbon dioxide kukukulirakulira m'makampani opanga mankhwala masiku ano, magwero akulosera kuti phulali likhoza kuwonedwa ngati molekyulu yosungiramo haidrojeni yogwira ntchito bwino mu chuma cha hydrogen chomwe chingakhalepo mtsogolo. Ndipotu, formic acid ndi zotumphukira zake zitha kuwonedwa ngati carbon dioxide yamadzimadzi yosungidwa yomwe ingagwiritsidwe ntchito mwachindunji mu unyolo wamtengo wapatali wa mankhwala womwe ulipo.
