Chemical Properties:

Acetic acid, CH3COOH, imvura isina ruvara, inovhuvhuta pane tembiricha yepakati.Mushonga wakachena, glacial acetic acid, une zita rawo nekuda kweaizi-yakafanana nekristaro kutaridzika pa15.6°C.Sezvinopihwa kazhinji, acetic acid ine 6 N aqueous solution (inenge 36%) kana 1 N mhinduro (inenge 6%).Izvi kana kuti zvimwe zvinwiwa zvinoshandiswa mukuwedzera zviyero zvakakodzera zveacetic acid kune zvekudya.Acetic asidhi ndiyo inoratidzika asidhi yevhiniga, iyo yakasarudzika kubva pa3.5 kusvika 5.6%.Acetic acid uye acetates zviripo mumiti yakawanda uye mhuka dzemhuka mune zviduku asi zvinoonekwa.Iwo akajairwa metabolic intermediates, anogadzirwa nemhando dzebhakitiriya dzakadai seAcetobacter uye anogona kugadzirwa zvachose kubva kucarbon dioxide nema microorganisms akadai seClostridium thermoaceticum.Iyo gonzo inoumba acetate pachiyero che1% yehuremu hwemuviri wayo pazuva.

Semvura isina ruvara ine kunhuhwirira kwakasimba, kunorwadza, kunhuhwirira kwevhiniga, inobatsira mubhotela, cheese, mazambiringa uye michero inonaka.Yakanyanya kudiki yakachena acetic acid seyakadaro inoshandiswa muzvikafu, kunyangwe ichiiswa muchikamu neFDA sechinhu cheGRAS.Nekuda kweizvozvo, inogona kushandiswa mune zvigadzirwa zvisina kufukidzwa neDefinitions uye Standards of Identity.Acetic acid ndiyo chikamu chikuru chevhiniga uye pyroligneous acid.Muchimiro chevhiniga, anopfuura mamirioni makumi maviri nenomwe lb akawedzerwa kuchikafu muna 1986, aine huwandu hwakaenzana hunoshandiswa se acidulants uye flavouring agents.Muchokwadi, acetic acid (sevhiniga) yaive imwe yepakutanga kunhuhwirira vamiririri.Mavhiniga anoshandiswa zvakanyanya mukugadzira saladhi yekupfeka uye mayonnaise, magaka anovava uye anotapira uye akawanda masosi uye katsi.Anoshandiswawo mukurapa nyama uye mumagaba emamwe muriwo.Mukugadzira mayonnaise, kuwedzerwa kwechikamu cheacetic acid (vhiniga) kune munyu- kana shuga-yolk inoderedza kupisa kweSalmonella.Mvura inosunga zvinyorwa zvemasoseji kazhinji inosanganisira acetic acid kana munyu wesodium, nepo calcium acetate inoshandiswa kuchengetedza kuumbwa kwemiriwo yakakangwa, yemumagaba.

Application:

Acetic acid inowanikwa muvhiniga.Inogadzirwa mukuparadza distillation yehuni.Inowana kushandiswa kwakakura muindasitiri yemakemikari.Inoshandiswa mukugadzira cellulose acetate, acetate rayon, uye akasiyana acetate uye acetyl makomisheni;sechinhu chinonyungudutsa chingamu, mafuta, uye resin;sechinhu chekuchengetedza chikafu mukudhinda nekudhaya;uye mune organicsynthesis.

Acetic acid chinhu chakakosha cheindasitiri chemakemikari.Kuita kweacetic acid ine hydroxyl ine makomboni, kunyanya madoro, inoguma nekuumbwa kweacetate esters.Kushandiswa kukuru kweacetic acid kuri mukugadzirwa kwevinyl acetate.Vinyl acetate inogona kugadzirwa kuburikidza nekuita kweacetylene uye acetic acid.Iyo zvakare inogadzirwa kubva ethylene uye acetic acid.Vinyl acetate yakaiswa polymerized kuita polyvinyl acetate (PVA), iyo inoshandiswa mukugadzira fiber, mafirimu, adhesives, uye latex pendi.
Cellulose acetate, iyo inoshandiswa mumachira uye firimu remifananidzo, inogadzirwa nekuita cellulose neacetic acid uye acetic anhydride pamberi pe sulfuric acid.Mamwe esters eacetic acid, akadai se ethyl acetate uye propyl acetate, anoshandiswa mune zvakasiyana-siyana zvekushandisa.
Acetic acid inoshandiswa kugadzira plastiki polyethylene terephthalate (PET).Acetic acid inoshandiswa kugadzira mishonga.

Glacial Acetic Acid is acidulant iri mvura yakajeka, isina ruvara ine acid inonaka kana yadirwa nemvura.Iyo i99.5% kana yakakwirira mukuchena uye inopenya pa17°c.Inoshandiswa mumapfekete e saladhi mune fomu yakasvibiswa kuti ipe acetic acid inodiwa.Inoshandiswa seanochengetedza, acidulant, uye flavoring agent.Inonzi zvakare acetic acid, glacial.
