Izici ze-Physicochemical:
1. Uketshezi olungenambala kanye ne-dour ecasulayo.
2. Iphuzu elincibilikayo 16.6 ℃; indawo yokubilisa 117.9 ℃; Iphoyinti elikhanyayo : 39 ℃.
3. Amanzi ancibilikayo, i-ethanol, i-benzene ne-ethyl ether immiscible, engancibiliki ku-carbon disulphide.
Isitoreji:
1. Igcinwe endaweni epholile, nengena umoya.
2. Gcina kude nomlilo, shisa. Isikhathi esibandayo kufanele sigcine izinga lokushisa elingaphezu kuka-16 ° C, ukuvimbela ukuqina. Ngesikhathi esibandayo, izinga lokushisa kufanele ligcinwe lingaphezu kuka-16 DEG C ukuvimbela/ukugwema ukuqina.
3. Gcina isitsha sivaliwe. Kufanele ihlukaniswe ne-oxidant ne-alkali. Ukuxuba kufanele kugwenywe ngazo zonke izindlela.
4. Sebenzisa izibani ezingaqhumi, izindawo zokungena komoya.
5. Imishini kanye namathuluzi avimbela ukusetshenziswa kwezinhlansi okulula ukukhiqiza.
6. Izindawo zokugcina kufanele zifakwe izinto zokwelashwa eziphuthumayo kanye nempahla yezindlu ezifanele.
Sebenzisa:
I-1.Okuphuma kuyo:Isetshenziswa kakhulu ekuhlanganiseni i-acetic anhydride,i-acetic ether,i-PTA, i-VAC/PVA, i-CA, i-ethonone, i-chloroacetic acid, njll.
2.Ezemithi:I-acetic acid njengezinto ezincibilikisayo nezinto zokusetshenziswa kwemithi, ikakhulukazi esetshenziselwa ukukhiqizwa kwe-penicilin G potas-sium, i-penicilin G sodium, i-penicillin procaine, i-acetanilide, i-sulfadiazine, ne-sulfamethoxazole isoxazole, i-norfloxacin, i-ciprofloxacin, i-acetinalic acid, i-acetinalic acid, i-acetinalic acid , i-caffeine, njll.
3.Okumaphakathi:i-acetate,i-sodium hydrogen di,i-peracetic acid, njll
4. Ukuphrinta kwendwangu kanye nokudaya kwendwangu: Isetshenziswa kakhulu ukukhiqiza odayi abahlakazayo namadayi we-vat, nokuphrinta kwezindwangu kanye nokucubungula ukudaya
5. I-synthesis ammonia: Ngendlela ye-cuprammonia acetate, esetshenziswa ekucwengisiseni ama-syngas ukususa i-litl CO ne-CO2
6. Isithombe: Unjiniyela
7. Irabha yemvelo: I-Coagulant
8. Imboni yezokwakha: Ukuvimbela ukhonkolo ekushiseni9. I-Addtin ibuye isetshenziswe kabanzi ekwelapheni amanzi, i-syntheticfiber, izibulala-zinambuzane, amapulasitiki, isikhumba, upende, ukucubungula insimbi kanye nemboni yenjoloba.
I-glacial acetic acid ivame ukubizwa ngokuthi i-acetic acid. Isixazululo se-glacial acetic acid singasetshenziswa emtholampilo ukwelapha izifo ezihlukahlukene zesikhunta sesikhumba, ngisho nezifo zesikhunta ezinzipho. Uma i-glacial acetic acid isetshenziselwa ukwelapha izifo zesikhunta, isisombululo esingu-30% se-glacial acetic acid sivame ukusetshenziswa. Isetshenziselwa ukwelapha izipikili ezimpunga, ezingasetshenziswa ngemva kokuhlanza izipikili ezigulayo nokunciphisa izipikili. Isikhumba esiseduze nozipho singavikelwa ngongqimba lwe-petroleum jelly. Lapho welapha ama-corns nama-warts esikhumbeni, kufanele uhlanze indawo enesifo ngaphambi kokusebenzisa umuthi, ucwiliswe emanzini ashisayo, bese usebenzisa umuthi. Kumele kuqashelwe ukuthi ngenxa yokuthi i-glacial acetic acid inomphumela othile wokugqwala, kungcono ukungasebenzisi izifo zesikhunta ebusweni. Uma usebenzisa, qiniseka ukuthi unake, ngaphezu kwe-lesion, ezinye izingxenye zesikhumba zingcono kakhulu ukusebenzisa i-Vaseline ukuvikela.
