Sebopeho sa kristale sa acetic acid se bontša hore limolek'hule li kopantsoe ho dimers (tse tsejoang hape e le dimers) ka li-hydrogen bonds, 'me li-dimers li boetse li teng sebakeng sa mouoane ka 120 ° C. Dimers li na le botsitso bo phahameng,' me ho ipakile hore li-carboxylic acid tse nang le boima bo tlaase ba limolek'hule tse kang formic acid le acetic acid e teng ka har'a mokhoa oa acetic le mokhoa oa acetic oa mokelikeli o teng ka har'a mokelikeli oa acetic. Boikemisetso ba boima ba limolek'hule ka ho fokotsa ntlha ea leqhoa le ho fapana ha X-ray. Ha acetic acid e qhibiliha ka metsi, maqhama a hydrogen pakeng tsa dimers a robeha kapele. Li-carboxylic acid tse ling li bonts'a dimerization e tšoanang.

1. asiti ea acetic ke sehlahisoa sa lik'hemik'hale tse ngata, ke e 'ngoe ea li-acid tse bohlokoa ka ho fetisisa. E sebelisoa haholo bakeng sa tlhahiso ea acetic anhydride, acetate le cellulose acetate. Polyvinyl acetate e ka etsoa lifilimi le li-adhesives, hape ke thepa e tala ea fiber ea maiketsetso ea Vinylon. Cellulose acetate e sebelisoa ho etsa rayon le filimi ea filimi.
2. ester ea acetic e entsoeng ka joala e tlaase ke solvent e babatsehang, e sebelisoang haholo indastering ea pente. Hobane asiti ea acetic e qhala boholo ba lintho tse phelang, e boetse e sebelisoa hangata joalo ka mokelikeli oa lintho tse phelang (mohlala, bakeng sa oxidation ea p-xylene ho hlahisa terephthalic acid).
3. asiti ea acetic e ka sebelisoa litharollong tse ling tsa pickling le polishing, ka tharollo e fokolang ea asiti e le buffer (joalo ka galvanized, electroless nickel plating), ka semi-bright nickel plating electrolyte e le tlatsetso, ka tharollo ea passivation ea zinki, cadmium e ka ntlafatsa matla a bonding ba acidity e tloaelehileng ea pH, e sebelisoang ka mokhoa o fokolang.
4. bakeng sa tlhahiso ea acetate, e kang manganese, sodium, lead, aluminium, zinki, cobalt le letsoai le leng la tšepe, tse sebelisoang haholo e le li-catalysts, ho daea lesela le lisebelisoa tsa indasteri ea ho sututsa letlalo; Acetate ea lead ke 'mala oa pente o mosoeu; Lead tetraacetate ke organic synthesis reagent (mohlala, lead tetraacetate e ka sebelisoa e le ntho e matla ea oxidizing, e fana ka mohloli oa acetoxy le ho lokisa metsoako ea loto ea manyolo, joalo-joalo).
5. asiti ea acetic e ka boela ea sebelisoa e le reagent analytical, organic synthesis, pigment le synthesis ea lithethefatsi.
Tšebeliso ea lijo
Indastering ea lijo, asiti ea acetic e sebelisoa e le acidifier, setlolo sa tatso le monko ha ho etsoa asene ea maiketsetso, asiti ea acetic e hlakotsoe ho 4-5% ka metsi, 'me litlolo tse fapaneng tsa tatso li eketsoa. Tatso e tšoana le ea asene ea joala, 'me nako ea tlhahiso e khutšoanyane' me theko e theko e tlaase. E le moemeli o bolila, e ka sebelisoa bakeng sa metsoako ea motsoako, ho lokisetsa asene, makotikoting, jelly le chisi, ho ea ka litlhoko tsa tlhahiso ea tšebeliso e nepahetseng. E ka boela ea etsa motsoako oa monko oa veine ea libano, palo ea tšebeliso ke 0.1 ~ 0.3 g/kg.
