Ngaba i-acetic acid iyafana ne-glacial acetic acid?,
I-Acetic Acid, umxholo we-acetic, Abavelisi beAcetic Acid, ababoneleli abavelisi be-acetic, Ababoneleli beAcetic Acid,
Ukucaciswa komgangatho (GB/T 1628-2008)

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, eyaziwa ngokuba yi-acetic acid (36% -38%), i-glacial acetic acid (98%), i-chemical formula CH3COOH, i-organic monic acid, inxalenye ephambili yeviniga. Pure anhydrous acetic acid (glacial acetic acid) yinto eqinileyo yehygroscopic engenambala enendawo yokukhenkce eyi 16.6 ° C (62 ° F) kwaye iba yikristale engenambala emva kokuqiniswa. Isinyibiliko saso esinamanzi sibuthathaka kwaye siyakhukuliseka, kwaye umphunga uyacaphukisa emehlweni nasempumlweni.

I-acetic acid ye-glacial (i-pure matter), oko kukuthi, i-acetic acid ene-anhydrous, i-organic compound. Iqina ibe ngumkhenkce kumaqondo obushushu aphantsi kwaye yaziwa njenge glacial acetic acid. Ukwandiswa kwevolumu ngexesha lokuqina kunokubangela ukuba isikhongozeli sigqabhuke. I-flash point yi-39℃, umda wokuqhuma ngu-4.0% ~ 16.0%, kwaye ubuninzi obuvumelekileyo bokugxininiswa emoyeni aludluli i-25mg / m3. I-acetic acid ecocekileyo iya kukhenkceka ibe ziikristale ezinjengomkhenkce ngaphantsi kwendawo yokunyibilika, ngoko ke i-acetic acid ene-anhydrous ikwabizwa ngokuba yi-glacial acetic acid.

Kuyabonakala ukuba ezi zimbini azifani, i-flash point ye-ice acetic acid yi-39 ℃, umda wokuqhuma ngu-4.0% ~ 16.0%, kwaye ubuninzi obuvumelekileyo bokugxininiswa emoyeni aludluli i-25mg / m3, eyeyabo. kwizinto ezinobungozi, kwaye i-acetic acid ayiyona impahla eyingozi.
