Lintho tsa Physicochemical:
1. Mokelikeli o se nang 'mala le dour e hlabang.
2. Ntho e qhibilihang 16.6 ℃; ntlha e belang 117.9 ℃; Ntlha ea Flash: 39 ℃.
3. Metsi a qhibilihang, ethanol, benzene le ethyl ether immiscible, a sa keneng ka har'a carbon disulphide.
Polokelo:
1. E bolokiloe ntlong ea polokelo e pholileng, e nang le moea o pholileng.
2. Boloka hole le mollo, mocheso. Sehla se batang se lokela ho boloka mocheso o fetang 16 ° C, ho thibela ho tiea. Nakong ea serame, mocheso o lokela ho bolokoa ka holimo ho 16 ° C ho thibela / ho qoba ho tiisa.
3. Boloka setshelo se tiisitsoe. E lokela ho aroloa ho tloha ho oxidant le alkali. Ho kopanya ho lokela ho qojoa ka mekhoa eohle.
4. Sebelisa mabone a thibelang ho phatloha, lisebelisoa tsa moea.
5. Lisebelisoa tsa mechine le lisebelisoa tse thibelang tšebeliso ea litlhase tse bonolo ho hlahisa.
6. Libaka tsa polokelo li lokela ho ba le thepa ea phekolo ea tšohanyetso le thepa e loketseng ea bolulo.
Sebelisa:
1.Derivative: Haholo-holo e sebelisoa ha ho etsoa acetic anhydride, acetic ether, PTA, VAC/PVA,CA, ethenone, chloroacetic acid, joalo-joalo.
2. Pharmaceutical:Acetic acid e le solvent le pharmaceuticalraw materials, haholo-holo e sebediswa bakeng sa tlhahiso ea penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, le sulfamethoxazole isoxazole, norfloxacin,ciprofloxalicy, acetinanisolic, acetinanisolic acid, prefloxacin, acetinanisolic, acetyl, sulfadiazine. , caffeine, joalo-joalo.
3.Intermediate: acetate, sodium hydrogen di, peracetic acid, joalo-joalo
4.Dyestuff le textile printing and dyeing: E sebelisoa haholo ho hlahisa lidae tse qhalakaneng le lidae tsa vat, le khatiso ea masela le ts'ebetso ea ho daea
5. Synthesis ammonia: Ka sebōpeho sa cuprammonia acetate, e sebelisoang ho hloekisa li-syngas ho tlosa litl CO le CO2.
6. Senepe: Moqapi

8. Indasteri ea kaho: Ho thibela konkreite ho tloha frezing9. In addtin e boetse e sebelisoa haholo kalafong ea metsi, li-syntheticfiber, chefo e bolaeang likokoanyana, polasetiki, letlalo, pente, ts'ebetso ea tšepe le indasteri ea rabara.
Ntlha ea pele, tlhaho e fapane
1, ice acetic acid: ke anhydrous acetic acid, acetic acid ke e 'ngoe ea li-organic acid, metsoako ea manyolo.
2, acetic acid: ke organic monic acid, e leng karolo ea mantlha ea asene.
Ea bobeli, litšobotsi tse fapaneng
1, glacial acetic acid: e tiea ho ba leqhoa mochesong o tlase, e tsejoang ka hore ke glacial acetic acid. Ho atolosoa ha molumo nakong ea ho tiisa ho ka etsa hore setshelo se phatlohe. Sebaka sa khanya ke 39 ℃, moeli oa ho phatloha ke 4.0% ~ 16.0%, 'me tekanyo e phahameng e amohelehang moeeng ha e fete 25mg / m3. Asiti e hloekileng ea acetic e tla hoama ka har'a likristale tse kang leqhoa ka tlase ho sebaka se qhibilihang, kahoo asiti ea anhydrous acetic e boetse e bitsoa glacial acetic acid.
2, asiti ea acetic: e na le 98% ea glacial acetic acid, sekhahla se lekanyelitsoeng (metsi ke 1) : 1.050; Viscosity (mPa.s) : 1.22 (20℃); Khatello ea mouoane ho 20 ℃ (KPa) : 1.5; Ponahalo le monko: Mokelikeli o senang mmala o monko o monate oa asiti ea asiti.
Tse tharo, lisebelisoa tse fapaneng
1, glacial acetic acid: e sebelisoa haholo bakeng sa ho qaptjoa ha vinyl acetate, acetate fiber, acetic anhydride, acetate, metal acetate le halogenated acetic acid. Hape ke thepa e tala ea bohlokoa bakeng sa meriana, dae, chefo e bolaeang likokoanyana le lintho tse ling tsa tlhaho.
2, asiti ea acetic: e ka sebelisoa e le taolo ea acidity, acidifier, pickling agent, flavoring, linoko, joalo-joalo.
