O le fausaga tioata o le acetic acid o loʻo faʻaalia ai o loʻo faʻapipiʻiina molelaʻau i dimers (lea e taʻua o dimers) e ala i le hydrogen bonds, ma o loʻo i ai foi le dimers i le tulaga ausa i le 120 ° C. Dimers e maualuga le mautu, ma ua faʻamaonia ai o le carboxylic acids ma le mamafa mole mole maualalo e pei o le formic acid ma le acetic acid o loʻo i ai i le tulaga o le mamafa o le kasa e ala i le mamafa o le kasa. fa'aitiitiga fa'a'aisa ma le fa'aeseesega o le X-ray. Pe a fa'amavae le acetic acid i le vai, e vave ona motusia sootaga o le hydrogen i le va o dimer. O isi acids carboxylic o lo'o fa'aalia tutusa le dimerization.

Fa'aaogaina o Mea
Fa'aaogāga fa'apisinisi
1. acetic acid o se oloa kemisi tele, o se tasi o acids organic sili ona taua. E masani ona faʻaaogaina mo le gaosiga o le acetic anhydride, acetate ma le cellulose acetate. O le Polyvinyl acetate e mafai ona faia i ata tifaga ma faʻapipiʻi, ma o le mea faʻapitoa foi o le fiber synthetic Vinylon. O le Cellulose acetate e faʻaaogaina e fai ai le rayon ma ata tifaga.
2. o le ester acetic faia e ava malosi maualalo o se solvent sili ona lelei, faʻaaogaina lautele i le fale vali. Talu ai ona o le acetic acid e fa'amavae ai le tele o mea fa'aola, e masani ona fa'aaogaina e fai ma so'o (fa'ata'ita'iga mo le fa'ama'iina o le p-xylene e maua ai le terephthalic acid).
3. acetic acid e mafai ona faaaoga i nisi vaifofo pickling ma polishing, i se vaifofo vaivai acidic e pei o se pa puipui (e pei o le galvanized, electroless nickel plating), i le electrolyte vili nickel semi-malamalama o se faaopoopoga, i le vaifofo passivation o le zinc, cadmium e mafai ona faaleleia atili le malosi fusi o le passivation taele, ma masani ona faaaoga le pH vaitaele vaivai.
4. mo le gaosiga o le acetate, e pei o le manganese, sodium, taʻitaʻi, alumini, zinc, cobalt ma isi uʻamea masima, faʻaaogaina lautele e pei o catalysts, vali ie ma paʻu paʻu alamanuia faaopoopo; Lead acetate o le vali lanu pa'epa'e; Lead tetraacetate o se mea faʻapipiʻi faʻapipiʻi faʻasolosolo (mo se faʻataʻitaʻiga, e mafai ona faʻaaogaina le tetraacetate taʻitaʻi e avea o se mea faʻamaʻi malosi, maua ai se puna o le acetoxy ma saunia mea faʻapipiʻi taʻitaʻi, ma isi).
5. acetic acid e mafai foi ona faʻaaogaina e avea o se suʻesuʻega suʻesuʻe, faʻasologa o meaola, pigmenti ma vailaʻau faʻasaina.
Fa'aaogāina o mea'ai
I totonu o le alamanuia o meaʻai, o loʻo faʻaaogaina le acetic acid e avea o se mea faʻamaʻi, mea manogi ma mea manogi pe a fai le vineka synthetic, o le acetic acid e faʻafefeteina i le 4-5% i le vai, ma faʻaopoopoina mea manogi eseese. O le tofo e talitutusa ma le vineka ava malosi, ma o le taimi o gaosiga e puupuu ma taugofie le tau. I le avea ai o se sui oona, e mafai ona faʻaaogaina mo faʻamaʻi faʻafefiloi, sauniuniga o le vineka, apa, jelly ma sisi, e tusa ai ma manaoga o le gaosiga o le faʻaoga talafeagai. E mafai foi ona fatuina le manogi e faʻaleleia ai le uaina mea manogi, o le aofaʻi o le faʻaaogaina o le 0.1 ~ 0.3 g / kg.
