Benzoic acid ndi cholimba choyera kapena makhiristo opanda mtundu ngati singano okhala ndi formula C6H5COOH. Lili ndi fungo losamveka bwino komanso lokoma. Chifukwa cha kusinthasintha kwake, asidi a benzoic amapeza ntchito m'mafakitale osiyanasiyana, kuphatikizapo kusunga zakudya, mankhwala, ndi zodzoladzola.

Benzoic acid ndi esters ake amapezeka mwachilengedwe mumitundu yosiyanasiyana ya zomera ndi nyama. Makamaka, zipatso zambiri zimakhala ndi zochulukirapo, pafupifupi 0.05%. Zipatso zakupsa za mitundu ingapo ya Vaccinium, monga kiranberi (V. vitis-idaea) ndi bilberry (V. myrtillus), zimatha kukhala ndi milingo yaulere ya benzoic acid kuyambira 0.03% mpaka 0.13%. Kuphatikiza apo, maapulo amapanga benzoic acid akagwidwa ndi bowa Nectria galligena. Kaphatikizidwe kameneka kapezekanso m’ziwalo zamkati ndi m’minofu ya rock ptarmigan (Lagopus muta), komanso mu glandular secretions of the male muskoxen (Ovibos moschatus) ndi Asian bull elephants (Elephas maximus). Kuphatikiza apo, chingamu benzoin imatha kukhala ndi 20% benzoic acid ndi 40% ya esters yake.

Benzoic acid, yochokera ku mafuta a cassia, ndi yabwino kwa zodzoladzola zomwe zimakhala ndi zomera.

Kugwiritsa ntchito Benzoic Acid

1. Kupanga phenol kumaphatikizapo kugwiritsa ntchito benzoic acid. Zatsimikiziridwa kuti phenol imachokera ku asidi a benzoic kupyolera mu mankhwala osungunuka a benzoic acid ndi mpweya wa okosijeni, mpweya wabwino, pamodzi ndi nthunzi pa kutentha kwa 200 ° C mpaka 250 ° C.

2. Benzoic acid imakhala ngati kalambulabwalo wa benzoyl chloride, yomwe imagwira ntchito yofunika kwambiri popanga mankhwala osiyanasiyana, utoto, fungo lonunkhira, herbicides, ndi mankhwala. Kuphatikiza apo, asidi a benzoic amatha kusintha kagayidwe kake kuti apange benzoate esters, benzoate amides, thioesters of benzoates, ndi benzoic anhydride. Ndilofunika kwambiri pamapangidwe ambiri ofunikira omwe amapezeka m'chilengedwe ndipo ndi ofunikira kwambiri pamankhwala achilengedwe.

3. Chimodzi mwazofunikira kwambiri za asidi a benzoic ndi monga chosungira mkati mwa gawo lazakudya. Amagwiritsidwa ntchito pafupipafupi muzakumwa, muzogulitsa zipatso, ndi sosi, komwe amagwira ntchito yofunika kwambiri poletsa kukula kwa nkhungu, yisiti, ndi mabakiteriya ena.

4. Pamalo a mankhwala, asidi a benzoic nthawi zambiri amaphatikizidwa ndi salicylic acid kuti athetse matenda a fungal pakhungu monga phazi la othamanga, zipere, ndi jock itch. Kuonjezera apo, amagwiritsidwa ntchito popanga ma topical formulations chifukwa cha zotsatira zake za keratolytic, zomwe zimathandiza kuchotsa njerewere, chimanga, ndi ma calluses. Akagwiritsidwa ntchito ngati mankhwala, benzoic acid nthawi zambiri amagwiritsidwa ntchito pamutu. Amapezeka m'njira zosiyanasiyana, kuphatikizapo zonona, mafuta odzola, ndi ufa. Kuchuluka kwa benzoic acid muzinthu izi nthawi zambiri kumayambira 5% mpaka 10%, nthawi zambiri amaphatikizidwa ndi salicylic acid. Pofuna kuchiza matenda oyamba ndi fungus pakhungu, ndikofunikira kuyeretsa ndi kuumitsa malo omwe akhudzidwa bwino musanagwiritse ntchito kagawo kakang'ono ka mankhwala. Kugwiritsa ntchito nthawi zambiri kumalimbikitsidwa kawiri kapena katatu patsiku, ndipo kutsatira malangizo a dokotala ndikofunikira kuti mupeze zotsatira zabwino.

Benzoic acid amawonedwa ngati otetezeka akagwiritsidwa ntchito moyenera; komabe, zingayambitse mavuto kwa anthu ena. Zotsatira zoyipa zomwe zimanenedwa pafupipafupi ndizomwe zimachitika pakhungu monga kufiira, kuyabwa, ndi kuyabwa. Zizindikirozi nthawi zambiri zimakhala zofatsa komanso zosakhalitsa, ngakhale zingakhale zovuta kwa ena. Ngati kupsa mtima kukupitilira kapena kukukulirakulira, ndikofunikira kusiya kugwiritsa ntchito mankhwalawa ndikupempha chitsogozo kwa akatswiri azachipatala.

Omwe ali ndi hypersensitivity yodziwika ku benzoic acid kapena chilichonse mwazinthu zake ayenera kupewa kugwiritsa ntchito zinthu zomwe zili ndi mankhwalawa. Kuonjezera apo, ndi contraindicated ntchito pa mabala otseguka kapena khungu losweka, monga mayamwidwe asidi kudzera pakhungu ngozi kungachititse zokhudza zonse kawopsedwe. Zizindikiro za kawopsedwe kazinthu zingaphatikizepo nseru, kusanza, kusapeza bwino m'mimba, komanso chizungulire, zomwe zimafunika kuthandizidwa mwachangu.

Amayi oyembekezera ndi oyamwitsa akulimbikitsidwa kukaonana ndi achipatala asanagwiritse ntchito mankhwala okhala ndi benzoic acid kuti adzitetezere okha ndi makanda awo. Ngakhale kuti umboni wokhudzana ndi zotsatira za benzoic acid pa nthawi ya mimba ndi kuyamwitsa ndi wochepa, nthawi zonse ndi bwino kuika patsogolo kusamala.

Mwachidule, benzoic acid ndi chinthu chamtengo wapatali chokhala ndi ntchito zambiri. Kapangidwe kake kachilengedwe, kasungidwe kake, komanso kusinthasintha kwake kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale osiyanasiyana. Komabe, ndikofunikira kugwiritsa ntchito benzoic acid mosamala komanso moyenera, kutsatira malangizo omwe akulimbikitsidwa ndikufunsana ndi dokotala pakafunika kutero.
