Chemical Properties:

Acetic acid, CH3COOH, ndi madzi opanda mtundu, osasunthika pa kutentha kozungulira.Gulu loyera, glacial acetic acid, limadziwika chifukwa cha mawonekedwe ake ngati ayezi pa 15.6 ° C.Monga momwe zimaperekedwa, asidi acetic ndi 6 N amadzimadzi yothetsera (pafupifupi 36%) kapena 1 N yankho (pafupifupi 6%).Mankhwalawa amagwiritsidwa ntchito powonjezera asidi woyenerera ku zakudya.Acetic asidi ndi khalidwe asidi viniga, ndende yake kuyambira 3.5 mpaka 5.6%.Acetic acid ndi acetates amapezeka muzomera zambiri ndi nyama zanyama zochepa koma zowoneka.Izi ndizomwe zimapangidwira kagayidwe kachakudya, amapangidwa ndi mitundu ya mabakiteriya monga Acetobacter ndipo amatha kupangidwa kwathunthu kuchokera ku carbon dioxide ndi tizilombo toyambitsa matenda monga Clostridium thermoaceticum.Makoswe amapanga acetate pamlingo wa 1% wa kulemera kwa thupi lake patsiku.

Monga colorless madzi ndi amphamvu, pungent, khalidwe vinyo wosasa fungo, ndi zothandiza batala, tchizi, mphesa ndi zipatso oonetsera.Acetic acid ochepa kwambiri monga choncho amagwiritsidwa ntchito muzakudya, ngakhale amagawidwa ndi FDA ngati zinthu za GRAS.Chifukwa chake, zitha kugwiritsidwa ntchito pazinthu zomwe sizikuphatikizidwa ndi Mafotokozedwe ndi Miyezo ya Identity.Acetic acid ndiye chigawo chachikulu cha vinegars ndi pyroligneous acid.Mu mawonekedwe a viniga, oposa 27 miliyoni lb anawonjezeredwa ku chakudya mu 1986, ndi pafupifupi ofanana ndalama ntchito ngati acidulants ndi flavoring agents.M'malo mwake, asidi acetic (monga viniga) anali amodzi mwazinthu zokometsera zakale kwambiri.Viniga amagwiritsidwa ntchito kwambiri pokonzekera saladi kuvala ndi mayonesi, pickles wowawasa ndi okoma ndi sauces ambiri ndi makatsups.Amagwiritsidwanso ntchito pochiritsa nyama ndi kuika m’zitini zamasamba.Popanga mayonesi, kuwonjezera gawo la acetic acid (vinyo wosasa) ku mchere kapena shuga-yolk kumachepetsa kukana kwa kutentha kwa Salmonella.Zomangamanga zamadzi za soseji nthawi zambiri zimakhala ndi acetic acid kapena mchere wake wa sodium, pomwe calcium acetate imagwiritsidwa ntchito kusunga mawonekedwe a masamba odulidwa, zamzitini.

Ntchito:
Kugwiritsa ntchito acetic acid m'mafakitale

1. Amagwiritsidwa ntchito popanga utoto ndi inki.

2. Amagwiritsidwa ntchito popanga mafuta onunkhira.

3. Amagwiritsidwa ntchito m'mafakitale a rabara ndi pulasitiki.Amagwiritsidwa ntchito ngati zosungunulira komanso zoyambira pama polima ambiri ofunikira m'makampani amphira ndi pulasitiki (monga PVA, PET, etc.).

4. Amagwiritsidwa ntchito ngati zoyambira zopangira utoto ndi zomatira

5. Amagwiritsidwa ntchito m'makampani opanga zakudya monga chowonjezera mu tchizi ndi sosi komanso ngati chosungira chakudya.

Kugwiritsa ntchito asidi acetic mu kaphatikizidwe ka mankhwala

1.Kugwiritsidwa ntchito popanga cellulose acetate.Cellulose acetate imagwiritsidwa ntchito m'mafilimu ndi zovala.Asanayambe kupanga filimu ya cellulose acetate, filimu yojambula zithunzi inkapangidwa ndi nitrate, yomwe inali ndi mavuto ambiri otetezera.

2. Ntchito monga zosungunulira kwa synthesis wa asidi terephthalic.Paraxylene ndi oxidized kukhala terephthalic acid.Terephthalic acid imagwiritsidwa ntchito popanga PET, yomwe imagwiritsidwa ntchito kwambiri popanga mabotolo apulasitiki.

3. Amagwiritsidwa ntchito kwambiri pochita ndi ma alcohols osiyanasiyana kuti apange esters.Zochokera ku Acetate zimagwiritsidwa ntchito kwambiri ngati zowonjezera chakudya.

4. Amagwiritsidwa ntchito popanga vinyl acetate monomer.The monomer kenako polymerized kupanga poly(vinyl acetate) amadziwikanso kuti PVA.pVA ili ndi ntchito zosiyanasiyana kuyambira zamankhwala (chifukwa cha biocompatibility to nanotechnology (monga stabilizer) mpaka kupanga mapepala).

5. Ntchito monga zosungunulira ambiri organocatalytic zimachitikira.

Kugwiritsa ntchito asidi acetic mu mankhwala

1. Asidi wa Acetic amagwiritsidwa ntchito mu njira yotchedwa pigmented endoscopy, yomwe ndi njira ina kuposa endoscopy wamba.

2. Acetic acid imagwiritsidwa ntchito poyang'anira khansa ya khomo lachiberekero ndi zotupa.Amagwiritsidwanso ntchito poyeza khansa ya pachibelekero.

3. Acetic acid amagwiritsidwa ntchito pochiza otitis kunja.

4. Acetic acid nthawi zina amagwiritsidwa ntchito pochiza matenda a bakiteriya ndi mafangasi.

5. M'mayesero a labotale pa mbewa, asidi acetic awonetsedwa kuti achepetse kuyankha kotupa mu mbewa.

Acetic acid amagwiritsidwa ntchito m'nyumba

1. Acetic acid ndi gawo lalikulu la viniga.

2. Viniga amagwiritsidwa ntchito potola masamba

3. Amagwiritsidwa ntchito popanga saladi

4. Amagwiritsidwa ntchito pophika.Imachita ndi soda kuti itulutse mpweya woipa wa carbon dioxide kuti chakudya chikhale chofewa.

5.Kugwiritsidwa ntchito ngati antifungal wothandizira.
