Benzoic acid ke solide e tšoeu kapa likristale tse se nang 'mala tse bopehileng joaloka nale ka foromo C6H5COOH. E na le monko o fokolang le o monate. Ka lebaka la thepa ea eona e fapaneng, asiti ea benzoic e sebelisoa liindastering tse fapaneng, ho kenyeletsoa ho boloka lijo, meriana le litlolo.

Benzoic acid le li-ester tsa eona li teng ka tlhaho mefuteng e fapaneng ea limela le liphoofolo. Ka ho hlakileng, monokotšoai o mongata o na le likhakanyo tse kholo, hoo e ka bang 0.05%. Litholoana tse butsoitseng tsa mefuta e mengata ea Vaccinium, joalo ka cranberry (V. vitis-idaea) le bilberry (V. myrtillus), e ka ba le maemo a mahala a benzoic acid ho tloha ho 0.03% ho isa ho 0.13%. Ho feta moo, liapole li hlahisa benzoic acid ha li tšoaelitsoe ke fungus Nectria galligena.

Ho feta moo, gum benzoin e ka ba le ho fihla ho 20% benzoic acid le 40% ea li-ester tsa eona.

Benzoic acid, e tsoang oli ea cassia, e loketse litlolo tse thehiloeng ho limela ka ho feletseng.

Tšebeliso ea Benzoic Acid

1. Tlhahiso ea phenol e kenyelletsa ho sebelisoa ha benzoic acid. Ho netefalitsoe hore phenol e ka nkuoa ho asiti ea benzoic ka ts'ebetso ea ho phekola asiti ea benzoic e qhibilihisitsoeng ka khase ea oxidizing, hantle ka moea, hammoho le mouoane ka mocheso ho tloha ho 200 ° C ho isa ho 250 ° C.

2. Benzoic acid e sebetsa e le selelekela sa benzoyl chloride, e phethang karolo ea bohlokoa tlhahisong ea mefuta e mengata ea lik'hemik'hale, lidae, litlolo tse nkhang hamonate, li-herbicides le meriana. Ho feta moo, asiti ea benzoic e kenella ka har'a metabolism ho etsa benzoate esters, benzoate amides, thioesters of benzoates, le benzoic anhydride. Ke ntho ea bohlokoa ka har'a metsoako e mengata ea bohlokoa e fumanoang tlhahong 'me e bohlokoa ho organic chemical.

3. E 'ngoe ea litšebeliso tse ka sehloohong tsa asiti ea benzoic ke setlolo se bolokang lijo ka har'a lekala la lijo. Hangata e sebelisoa linong, lihlahisoa tsa litholoana le lisoseng, moo e phethang karolo ea bohlokoa ho thibeleng ho hōla ha hlobo, litomoso le libaktheria tse itseng.

4. Sebakeng sa meriana, acid ea benzoic hangata e kopantsoe le salicylic acid ho sebetsana le maemo a letlalo a fungal a kang leoto la moatlelete, ringworm le jock itch. Ho feta moo, e sebelisoa mefuteng ea lihlooho ka lebaka la litlamorao tsa eona tsa keratolytic, tse thusang ho tlosoa ha li-warts, poone le li-calluses. Ha e sebelisoa molemong oa ho phekola, asiti ea benzoic hangata e sebelisoa ka holimo. E fumaneha ka mefuta e fapaneng, ho kenyelletsa litlolo, litlolo le phofo. Khatello ea asiti ea benzoic lihlahisoa tsena hangata e tloha ho 5% ho isa ho 10%, hangata e kopantsoe le motsoako o tšoanang oa salicylic acid. Bakeng sa phekolo e sebetsang ea mafu a fungal letlalong, ke habohlokoa ho hloekisa le ho omisa sebaka se amehileng hantle pele u sebelisa lesela le lesesaane la meriana. Hangata kopo e khothaletsoa habeli ho isa ho hararo ka letsatsi, 'me ho latela tataiso ea setsebi sa tlhokomelo ea bophelo ke habohlokoa bakeng sa ho fumana liphello tse molemohali.

Benzoic acid e nkoa e sireletsehile ha e sebelisoa ka nepo; leha ho le joalo, ho ka baka litla-morao ho batho ba itseng. Litla-morao tse tlalehiloeng khafetsa li kenyelletsa ho fetoha ha letlalo sebakeng se kang bofubelu, ho hlohlona, ​​le ho teneha. Matšoao ana ka kakaretso ha a bonolo ebile a na le nakoana, le hoja a ka ba thata ho ba bang. Haeba ho teneha ho ntse ho tsoela pele kapa ho tota, ho eletsoa ho emisa ho sebelisa sehlahisoa 'me u batle tataiso ho tsoa ho setsebi sa tlhokomelo ea bophelo.

Ba nang le hypersensitivity e tsebahalang ho benzoic acid kapa metsoako efe kapa efe ea eona ba lokela ho qoba ho sebelisa lihlahisoa tse nang le motsoako ona. Ho feta moo, e hanetsoe ho sebelisoa maqeba a bulehileng kapa letlalo le robehileng, kaha ho monya ha acid ka letlalo le sekiselitsoeng ho ka baka chefo ea systemic. Matšoao a toxicity ea tsamaiso a ka 'na a kenyelletsa ho nyekeloa ke pelo, ho hlatsa, ho se utloise bohloko ka mpeng, le ho tsekela, ho hloka ho kenella hang-hang ho tsa bongaka.

Basali ba bakhachane le ba anyesang ba khothaletsoa ho buisana le mofani oa bona oa tlhokomelo ea bophelo pele ba sebelisa lihlahisoa tse nang le benzoic acid ho netefatsa polokeho bakeng sa bona le masea a bona. Le hoja bopaki bo mabapi le liphello tsa benzoic acid nakong ea bokhachane le lactation bo lekanyelitsoe, kamehla ke bohlale ho beha tlhokomelo pele.

Ka bokhutšoanyane, benzoic acid ke motsoako oa bohlokoa o nang le mefuta e mengata ea lisebelisoa. Ho ba teng ha eona ka tlhaho, matla a ho baballa, le ho feto-fetoha ha maemo ho etsa hore e be karolo ea bohlokoa liindastering tse fapaneng. Leha ho le joalo, ho bohlokoa ho sebelisa benzoic acid ka mokhoa o sireletsehileng le ka boikarabelo, ho latela litataiso tse khothaletsoang le ho buisana le setsebi sa tlhokomelo ea bophelo ha ho hlokahala.
