Na Waiwai Kemika:

ʻO ka ʻakika Acetic, CH3COOH, he wai waihoʻoluʻu ʻole i nā mahana ambient. ʻO ka pūhui maʻemaʻe, glacial acetic acid, nona ka inoa i kona ʻano aniani like me ka hau ma 15.6°C. E like me ka mea maʻamau, ʻo ka ʻakika acetic he 6 N ka hopena wai (ma kahi o 36%) a i ʻole ka hopena 1 N (ma kahi o 6%). Hoʻohana ʻia kēia a i ʻole nā ​​​​mea hoʻoheheʻe ʻē aʻe i ka hoʻohui ʻana i ka nui o ka acetic acid i nā meaʻai. ʻO ka waikawa Acetic ka waika maʻamau o ka vīnega, ʻo kona ʻike mai 3.5 a 5.6%. Aia ka Acetic acid a me ka acetates i ka hapa nui o nā mea kanu a me nā ʻiʻo holoholona i ka liʻiliʻi akā hiki ke ʻike ʻia. ʻO lākou nā mea maʻamau metabolic intermediates, i hana ʻia e nā ʻano bacteria e like me Acetobacter a hiki ke synthesized piha mai carbon dioxide e nā microorganism e like me Clostridium thermoaceticum. Hoʻokumu ka ʻiole i ka acetate ma ka helu o 1% o kona kaumaha kino i kēlā me kēia lā.

Ma ke ʻano he wai kala ʻole me ka ʻala ikaika a me ke ʻano o ka vīnega, pono ia i ka pata, ka paʻakai, ka hua waina a me nā ʻono hua. ʻAʻole liʻiliʻi ka ʻakika acetic maʻemaʻe e like me ia i hoʻohana ʻia i nā meaʻai, ʻoiai ua helu ʻia e FDA ma ke ʻano he mea GRAS. No laila, hiki ke hoʻohana ʻia i nā huahana i uhi ʻole ʻia e nā wehewehe a me nā kūlana o ka ʻike. ʻO ka waikawa Acetic ka mea nui o ka vīnega a me ka waikawa pyroligneous. Ma ke ʻano o ka vīneka, ʻoi aku ma mua o 27 miliona lb i hoʻohui ʻia i ka meaʻai i ka makahiki 1986, me ka nui o nā mea like i hoʻohana ʻia e like me nā acidulants a me nā mea ʻono. ʻO ka ʻoiaʻiʻo, ʻo ka acetic acid (e like me ka vīnega) kekahi o nā mea ʻono mua loa. Hoʻohana nui ʻia ka vinega i ka hoʻomākaukau ʻana i ka ʻaʻahu salakeke a me ka mayonnaise, nā pīkī ʻawaʻawa a me ka ʻono a me nā ʻuala he nui a me nā pōpoki. Hoʻohana ʻia lākou i ka hoʻōla ʻana i ka ʻiʻo a me ke kīʻaha ʻana i kekahi mau mea kanu. I ka hana ʻana i ka mayonnaise, ʻo ka hoʻohui ʻana o kahi ʻāpana o ka acetic acid (vinegar) i ka paʻakai a i ʻole ke kō-yolk e hoʻemi i ka pale wela o Salmonella. Hoʻokomo pinepine ʻia ka ʻakika acetic a i ʻole ka paʻakai sodium i ka hui paʻa wai o nā sausages, ʻoiai hoʻohana ʻia ka calcium acetate no ka mālama ʻana i ke ʻano o nā mea kanu i kālai ʻia.

Noi:
Hoʻohana i ka acetic acid i ka ʻoihana

1. Hoʻohana ʻia i ka synthesis o nā mea pena a me nā inika.

2. Hoʻohana ʻia ia i ka synthesis o nā mea ʻala.

3. Hoʻohana ʻia ia i loko o nā ʻoihana palaki a me ka plastic. Hoʻohana ʻia ia ma ke ʻano he solvent a me ka hoʻomaka ʻana no nā polymers koʻikoʻi i loko o nā ʻoihana palaki a me ka plastic (e like me PVA, PET, etc.).

4. Hoʻohana ʻia ia ma ke ʻano he mea hoʻomaka no ka pena a me nā mea hoʻopili

5. Hoʻohana ʻia i ka ʻoihana hana meaʻai ma ke ʻano he mea hoʻohui i ka paʻakai a me nā meaʻai a me ka mālama ʻana i ka meaʻai.

Ka hoʻohana ʻana i ka ʻakika acetic i ka synthesis kemika

1.Hoʻohana i ka synthesis o cellulose acetate. Hoʻohana ʻia ka cellulose acetate i nā kiʻiʻoniʻoni kiʻi a me nā textiles. Ma mua o ka hana ʻia ʻana o cellulose acetate film, hana ʻia ke kiʻi kiʻi me ka nitrate, a he nui nā pilikia palekana.

2. Hoʻohana ʻia e like me ka solvent no ka synthesis o terephthalic acid. Hoʻopili ʻia ka paraxylene i ka waikawa terephthalic. Hoʻohana ʻia ʻo Terephthalic acid e synthesize i ka PET, ka mea i hoʻohana nui ʻia e hana i nā hue plastik.

3. Hoʻohana nui ʻia i ka hopena me nā ʻano ʻona like ʻole e synthesize esters. Hoʻohana nui ʻia nā derivatives acetate e like me nā mea hoʻohui meaʻai.

4. Hoʻohana ʻia i ka synthesis o vinyl acetate monomer. A laila hiki ke polymerized ka monomer e hana i ka poly(vinyl acetate) i ʻike pinepine ʻia ʻo PVA. Loaʻa i ka pVA ka nui o nā noi mai ka lāʻau lapaʻau (ma muli o kona biocompatibility i ka nanotechnology (ma ke ʻano he stabilizer) i ka hana pepa).

5. Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe i nā hopena organocatalytic he nui.

Hoʻohana i ka acetic acid i ka lāʻau lapaʻau

1. Hoʻohana ʻia ka ʻakika acetic i kahi ʻenehana i kapa ʻia ʻo pigmented endoscopy, kahi mea ʻokoʻa i ka endoscopy maʻamau.

2. Hoʻohana ʻia ka Acetic acid no ka nānā ʻana i ka maʻi maʻi cervical a me nā ʻeha. Hoʻohana ʻia ia no ka nānā ʻana i ka maʻi kanesa cervical.

3. Hoʻohana ʻia ka Acetic acid e mālama i ka otitis externa.

4. Hoʻohana ʻia ka waikawa acetic i kekahi manawa no ka mālama ʻana i nā maʻi bacterial a me nā maʻi fungal.

5. Ma nā hoʻokolohua hoʻokolohua ma nā ʻiole, ua hōʻike ʻia ka acetic acid e hōʻemi i ka pane inflammatory i nā ʻiole.

ʻO ka hoʻohana ʻana i ka waika acetic i ka hale

1. ʻO ka waikawa Acetic ka mea nui o ka vīneka.

2. Hoʻohana ʻia ka vīneka no ka ʻohi ʻana i nā mea kanu

3. Hoʻohana ʻia ia no ka ʻaʻahu saladi

4. Hoʻohana ʻia ia i ka hana kuke. Hoʻopili ʻo ia me ka soda baking no ka hoʻokuʻu ʻana i ke kinoea carbon dioxide e hoʻoheheʻe i ka meaʻai.

5.Hoʻohana ma ke ʻano he antifungal agent.
