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:

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

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

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

4. Hoʻohana ʻia ia i mea hoʻomaka no ka pena a me nā mea hoʻopili

5. Hoʻohana ʻia ia 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.

Acetic acid - Palekana

LD50 waha no nā ʻiole: 3530mg/kg; LDso percutaneous no nā lākeke: 1060mg/kg; inhalation thLC50 no nā ʻiole: 13791mg/m3. ʻinoʻino. ʻO ka inhalation o kēia mahu huahana he mea hoʻonāukiuki i ka ihu, ka puʻu a me ka ʻōpū hanu. Hoonaukiuki loa i na maka. Palekana, holoi me ka wai kahe. ʻAʻole loa e hui pū me ka oxidizer, alkali, edible chemical, etc. E kūʻai i loko o kahi hale kūʻai anuanu. E mālama i ke ahi a me nā kumu wela. E hoʻopaʻa i ka pahu. E kūʻai kaʻawale mai nā oxidizer a me nā alkali.
