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-acetic acid ye-glacial (i-pure matter), oko kukuthi, i-acetic acid e-anhydrous, i-acetic acid yenye yezinto ezibalulekileyo eziphilayo, i-organic compounds. Iqina ibe ngumkhenkce kwiqondo lobushushu eliphantsi, eyaziwa njenge glacial acetic acid. Ukwandiswa kwevolumu ngexesha lokuqina kunokubangela ukuba isikhongozeli siphuke. I-Flash point 39℃, umda wokuqhuma kwe-4.0% ~ 16.0%, ubuninzi bogxininiso obuvumelekileyo emoyeni alikho ngaphezu kwe-25mg / m3. I-acetic acid ecocekileyo iya kuba ngumkhenkce kwiikristale zomkhenkce ngaphantsi kwendawo yokunyibilika, ngoko ke i-acetic acid ene-anhydrous ikwabizwa ngokuba yi-glacial acetic acid.
sebenzisa
Isicelo: Isetyenziselwa kakhulu ukudibanisa i-vinyl acetate, i-acetate fiber, i-acetic anhydride, i-acetate, i-acetate yensimbi kunye ne-halogenated acetic acid. Ikwayinto ebalulekileyo ekrwada kwiyeza, idayi, i-pesticide kunye nezinye izinto eziphilayo. Ukongeza, ikwasetyenziswa kakhulu ekwenzeni amachiza okufota, i-cellulose acetate, ushicilelo lwelaphu kunye nokudaya kunye namashishini erabha, izinyibilikisi zokwenza iiplastiki, iidayi, ukufota, amayeza, izibulali zinambuzane kunye nezinye izinto ezikrwada ze-organic synthesis.
