Ubume bekristale be-acetic acid bubonisa ukuba iimolekyuli ziboshwe kwiidimers (ezaziwa ngokuba zii-dimers) ngamabhondi e-hydrogen, kwaye iidimers zikwakhona kwimo yomphunga kwi-120 ° C. I-Dimers inozinzo oluphezulu, kwaye kuye kwangqinwa ukuba i-carboxylic acids ezinobunzima obuphantsi bemolekyuli njengefomikhali ye-asidi kunye ne-acetic yemeko yolwelo okanye i-asidi ye-acetic ekhoyo kwindlela yolwelo okanye i-acetic acid. ukuzimisela ubunzima bemolekyuli ngokunciphisa indawo yokukhenkceza kunye ne-X-ray diffraction. Xa i-acetic acid inyibilika ngamanzi, iibhondi zehydrogen phakathi kweedimers ziyaqhawuka ngokukhawuleza. Ezinye iiasidi ze-carboxylic zibonisa ukuncipha okufanayo.

Ukusetyenziswa kweMveliso
Ukusetyenziswa kwamashishini
1. i-acetic acid yimveliso yeekhemikhali ezininzi, yenye yezona zinto zibalulekileyo ze-organic acids. Isetyenziselwa ikakhulu ukuveliswa kwe-acetic anhydride, i-acetate kunye ne-cellulose acetate. I-acetate ye-Polyvinyl inokwenziwa kwiifilimu kunye ne-adhesives, kwaye iphinda ibe yimathiriyeli ekrwada ye-synthetic fiber Vinylon. I-cellulose acetate isetyenziselwa ukwenza i-rayon kunye nefilimu yomfanekiso oshukumayo.
2. i-acetic ester eyenziwe ngama-alcohols aphantsi yi-solvent egqwesileyo, esetyenziswa ngokubanzi kwishishini lepeyinti. Ngenxa yokuba i-acetic acid inyibilikisa i-organic matter, isetyenziswa ngokuqhelekileyo njenge-solvent ye-organic (umzekelo, i-oxidation ye-p-xylene ukuvelisa i-terephthalic acid).
3. iacetic acid ingasetyenziswa kwezinye izisombululo zokuchola kunye nokupolisha, kwisisombululo esibuthathaka esineasidi njengesithinteli (esifana negalvanized, electroless nickel plating), kwi-nickel semi-bright plating electrolyte njenge-additive, kwisisombululo se-passivation se-zinc, i-cadmium inokuphucula amandla okudibanisa i-acidic kunye nokulungelelanisa i-acidic eqhelekileyo ye-asidi esetyenziswayo kunye ne-acidic esebenzayo kwi-pH.
4. ukwenzela ukuveliswa kwe-acetate, efana ne-manganese, i-sodium, i-lead, i-aluminium, i-zinc, i-cobalt kunye nezinye iityuwa zetsimbi, ezisetyenziswa ngokubanzi njenge-catalysts, ukudaya kwelaphu kunye nezongezo ze-leather tanning; I-acetate yelothe ngumbala wepeyinti omhlophe; I-lead tetraacetate yi-organic synthesis reagent (umzekelo, i-tetraacetate ekhokelayo ingasetyenziselwa njenge-agent eqinile ye-oxidizing, inike umthombo we-acetoxy kwaye ilungiselele i-organic lead compounds, njl.).
5. i-acetic acid ingasetyenziselwa njenge-reagent analytical, i-organic synthesis, i-pigment kunye ne-chiza synthesis.
Ukusetyenziswa kokutya
Kwishishini lokutya, i-acetic acid isetyenziswe njenge-acidifier, i-agent agent kunye nephunga elimnandi xa isenza iviniga yokwenziwa, i-acetic acid ihlanjululwe kwi-4-5% ngamanzi, kunye neentlobo ezahlukeneyo ze-flavoring agents zongezwa. I-flavour ifana neviniga enxilisayo, kwaye ixesha lokuvelisa lifutshane kwaye ixabiso lincinci. Njenge-ejenti emuncu, ingasetyenziselwa i-seasoning edibeneyo, ukulungiswa kweviniga, i-canned, i-jelly kunye noshizi, ngokweemfuno zemveliso zokusetyenziswa okufanelekileyo. Isenakho nokuqulunqa isixhasi sevumba lewayini yesiqhumiso, ubungakanani bokusetyenziswa yi-0.1 ~ 0.3 g/kg.
