Iimpawu zePhysicochemical:
1. Ulwelo olungenambala kunye ne-dour ecaphukisayo.
2. Indawo yokunyibilika 16.6 ℃; indawo yokubilisa 117.9℃; Indawo edanyazayo: 39 ℃.
3. Amanzi anyibilikayo, i-ethanol, ibenzene kunye ne-ethyl ether immiscible, enganyibilikiyo kwicarbon disulphide.
Ugcino:
1. Igcinwe kwindawo epholileyo, nengena umoya.
2. Gcina kude nomlilo, shushu. Ixesha elibandayo kufuneka ligcine ubushushu obungaphezulu kwe-16 DEG C, ukuthintela ukuqina. Ngexesha elibandayo, ubushushu kufuneka bugcinwe ngaphezu kwe-16 DEG C ukunqanda/ukuphepha ukuqina.
3. Gcina isitya sivaliwe. Kufuneka yahlulwe kwi-oxidant kunye ne-alkali. Ukuxuba kufuneka kuphetshwe ngazo zonke iindlela.
4. Sebenzisa izibane ezingagqabhukiyo, izixhobo zokungenisa umoya.
5. Izixhobo zoomatshini kunye nezixhobo ezivimbela ukusetyenziswa kwezinto ezilula ukuvelisa iintlantsi.
6. Iindawo zokugcina kufuneka zixhotyiswe ngezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zezindlu.
Sebenzisa:
1.I-Derivative: Isetyenziswa kakhulu ekwenzeni i-acetic anhydride, i-acetic ether, i-PTA, i-VAC/PVA, i-CA, i-ethanone, i-chloroacetic acid, njl.
2.Pharmaceutical:Acetic acid as solvent and pharmaceuticalraw materials, ikakhulu esetyenziselwa imveliso penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, kunye sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetinelic acid, acetyl, preacetyl ,icaffeine, njl.
3.Ephakathi:iacetate,sodium hydrogen di,peracetic acid, njl
4. Idayi kunye noshicilelo olulukiweyo kunye nokudaya: Isetyenziswa kakhulu ukuvelisa iidayi ezisasazwayo kunye nedayi yevat, kunye nokuprintwa kwelaphu kunye nokudaywa
5. I-Synthesis ammonia: Ikwimo ye-cuprammonia acetate, esetyenziswa ekusulungekiseni i-syngas ukususa i-litl CO kunye ne-CO2
6. Ifoto: uMphuhlisi
7. Irabha yendalo: I-Coagulant
8. Ushishino lokwakha: Ukuthintela ikhonkrithi ekukhenkceni9. Kwi-addtin ikwasetyenziswa ngokubanzi kunyango lwamanzi, i-syntheticfiber, i-pesticides, iiplastiki, ufele, ipeyinti, ukusetyenzwa kwesinyithi kunye neshishini lerubha.
I-glacial acetic acid, ebizwa ngokuba yi-glacial acetic acid, i-acetic acid okanye i-acetic acid, i-organic compound, i-chemical formula CH3COOH, i-organic monic acid, eyona nxalenye yeviniga. Pure anhydrous acetic acid (glacial acetic acid) lulwelo olungenambala lwehygroscopic olunendawo yokukhenkceza eyi-16.6 ° C (62 ° F). Emva kokuqina, iba yikristale engenambala, eneasidi ebuthathaka kwaye idlakazeke kwisisombululo sayo esinamanzi. Iyingozi kakhulu kwisinyithi, kwaye umphunga uyacaphukisa emehlweni nasempumlweni. I-acetic acid isasazwa ngokubanzi kwindalo, njengeziqhamo okanye i-oyile yemifuno, ngokukodwa kwi-esters. I-acetic acid ikhona njenge-asidi yamahhala kwizicubu zezilwanyana, i-excreta kunye negazi. Iimicroorganisms ezininzi zinokuguqula izinto ezahlukeneyo eziphilayo zibe yi-acetic acid ngokuvundiswa.
