Hōʻike ke ʻano aniani o ka ʻakika acetic ua hoʻopaʻa ʻia nā molekala i nā dimer (ʻike ʻia ʻo dimers) e nā paʻa hydrogen, a ʻo nā dimer pū kekahi i loko o ka moku mahu ma 120 ° C. He kiʻekiʻe ke kūpaʻa o nā dimer, a ua hōʻike ʻia he carboxylic. ʻO nā ʻakika me ke kaumaha molekala haʻahaʻa e like me ka formic acid a me ka acetic acid aia ma ke ʻano o nā dimer ma ke ʻano paʻa, wai a i ʻole ke kinoea ma ke ʻano o ka hoʻoholo ʻana i ke kaumaha molekala ma o ka hōʻemi ʻana i ka helu hau a me ka diffraction X-ray.Ke hoʻoheheʻe ʻia ka ʻakika acetic me ka wai, e haki koke nā paʻa hydrogen ma waena o nā dimer.Hōʻike like nā ʻakika carboxylic ʻē aʻe.

Hoʻohana ʻenehana
1. ʻO ka ʻakika acetic kahi huahana kemika nui, ʻo ia kekahi o nā mea waiwai nui.Hoʻohana nui ia no ka hana ʻana i ka acetic anhydride, acetate a me cellulose acetate.Hiki ke hana ʻia ka polyvinyl acetate i nā kiʻiʻoniʻoni a me nā mea hoʻopili, a ʻo ia hoʻi ka mea maka o ka synthetic fiber Vinylon.Hoʻohana ʻia ka cellulose acetate e hana i ka rayon a me ke kiʻi ʻoniʻoni.
2. ʻO ka ester acetic i hana ʻia e nā waiʻona haʻahaʻa he mea hoʻoheheʻe maikaʻi loa, hoʻohana nui ʻia i ka ʻoihana pena.Ma muli o ka hoʻoheheʻe ʻana o ka ʻakika acetic i ka nui o nā mea olaola, hoʻohana mau ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe kūlohelohe (e laʻa no ka hoʻoheheʻe ʻana o ka p-xylene e hoʻohua ai i ka waikawa terephthalic).
3. hiki ke hoʻohana 'ia ka acetic acid i loko o kekahi pickling a me ka polishing solutions, i loko o ka solution acidic weakly as buffer (e like me galvanized, electroless nickel plating), i ka nickel plating electrolyte semi-bright ma ke ano he additive, i ka hopena passivation o zinc. , hiki i ka cadmium ke hoʻomaikaʻi i ka ikaika paʻa o ke kiʻi passivation, a hoʻohana mau ʻia e hoʻoponopono i ka pH o ka wai ʻauʻau nāwaliwali.
4. no ka hana ʻana i ka acetate, e like me ka manganese, sodium, ke kēpau, aluminika, zinc, cobalt a me nā paʻakai metala ʻē aʻe, hoʻohana nui ʻia e like me nā catalysts, nā lole lole a me nā mea hoʻohui ʻoihana tanning ʻili;ʻO ke alakaʻi acetate ke kala kepau keʻokeʻo;ʻO ka Lead tetraacetate kahi mea hoʻoheheʻe organik synthesis (no ka laʻana, hiki ke hoʻohana ʻia ka tetraacetate alakaʻi ma ke ʻano he mea hoʻoheheʻe ikaika, hāʻawi i kahi kumu o ka acetoxy a hoʻomākaukau i nā pūhui alakaʻi organik, etc.).
5. Hiki ke hoʻohana ʻia ka acetic acid ma ke ʻano he analytical reagent, organic synthesis, pigment a me ka lāʻau synthesis.
Hoʻohana meaʻai
I ka ʻoihana meaʻai, hoʻohana ʻia ka acetic acid ma ke ʻano he acidifier, mea ʻala a me nā mea ʻala i ka wā e hana ai i ka vīnega synthetic, ua hoʻoheheʻe ʻia ka acetic acid i ka 4-5% me ka wai, a hoʻohui ʻia nā mea ʻono like ʻole.Ua like ka ʻono me ka vīnega ʻawaʻawa, a he pōkole ka manawa hana a he ʻuʻuku ke kumu kūʻai.Ma ke ʻano he mea ʻawaʻawa, hiki ke hoʻohana ʻia no ka hoʻohuihui ʻana, hoʻomākaukau i ka vīneka, canned, jelly a me ka paʻakai, e like me nā pono hana o ka hoʻohana kūpono.Hiki iā ia ke haku i ka mea hoʻonui ʻala o ka waina ʻala, ʻo ka nui o ka hoʻohana ʻana he 0.1 ~ 0.3 g / kg.
