Kodi pali kusiyana kotani pakati pa glacial acetic acid ndi acetic acid,
Acetic Acid, Glacial Acetic Acid, glacial acetic acid zochita ndi ntchito, Opanga glacial acetic acid, kugwiritsa ntchito glacial asidi,
Makhalidwe abwino (GB/T 1628-2008)

Physicochemical katundu:
1. Zamadzimadzi zopanda mtundu komanso zowawa.
2. Malo osungunuka 16.6 ℃; kutentha kwa 117.9 ℃; Kuwala kwapakati: 39 ℃.
3. Madzi osungunuka, ethanol, benzene ndi ethyl ether immiscible, osasungunuka mu carbon disulphide.
Posungira:
1. Zosungidwa m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino.
2. Khalani kutali ndi moto, kutentha. Nyengo yozizira iyenera kukhalabe kutentha kuposa 16 ° C, kupewa kulimba. M'nyengo yozizira, kutentha kuyenera kusungidwa pamwamba pa 16 DEG C kuti mupewe / kupewa kulimba.
3. Sungani chidebe chosindikizidwa. Ayenera kupatulidwa ndi okosijeni ndi zamchere. Kusakaniza kuyenera kupewedwa mwa njira zonse.
4. Gwiritsani ntchito kuyatsa kosaphulika, malo olowera mpweya.
5. Zipangizo zamakina ndi zida zomwe zimaletsa kugwiritsa ntchito zosavuta kupanga zopsereza.
6. Malo osungiramo zinthu ayenera kukhala ndi zipangizo zothandizira chithandizo chadzidzidzi komanso zipangizo zoyenera zapanyumba.
Gwiritsani ntchito:
1.Drivative: Amagwiritsidwa ntchito popanga acetic anhydride, acetic etha, PTA, VAC/PVA, CA, ethenone, chloroacetic acid, etc.
2.Pharmaceutical:Acetic acid monga zosungunulira ndi mankhwala zopangira mankhwala, makamaka ntchito kupanga penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, ndi sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetinanisolic asidi, acetinanisolic, acetinanisolic asidi , caffeine, etc.
3. Yapakatikati: acetate, sodium hydrogen di, peracetic acid, etc
4.Dyestuff ndi nsalu yosindikiza ndi utoto: Amagwiritsidwa ntchito kwambiri popanga utoto wobalalitsa ndi utoto wa vat, ndi kusindikiza kwa nsalu ndi kukonza utoto
5. Kaphatikizidwe ammonia: Mu mawonekedwe a cuprammonia acetate, ntchito kuyenga syngas kuchotsa litl CO ndi CO2
6. Chithunzi: Wopanga
7. Labala lachilengedwe: Coagulant
8. Makampani omangamanga: Kupewa konkire ku frezing9. Mu addtin amagwiritsidwanso ntchito kwambiri pochiza madzi, syntheticfiber, mankhwala ophera tizilombo, mapulasitiki, zikopa, utoto, kukonza zitsulo ndimakampani amphira.
Choyamba, chilengedwe ndi chosiyana
1, ice acetic acid: ndi anhydrous acetic acid, asidi acetic ndi imodzi mwazinthu zofunika kwambiri za organic, organic mankhwala.
2, asidi asidi: ndi organic monic asidi, chigawo chachikulu cha viniga.
Chachiwiri, makhalidwe osiyanasiyana
1, glacial acetic acid: imakhazikika mu ayezi pa kutentha kochepa, komwe kumadziwika kuti glacial acetic acid. Kuwonjezeka kwa voliyumu panthawi yolimba kungayambitse chidebecho kuphulika. Kung'anima ndi 39 ℃, malire a kuphulika ndi 4.0% ~ 16.0%, ndipo kuchuluka kovomerezeka mumlengalenga sikudutsa 25mg/m3. Acetic acid yoyera imaundana kukhala makhiristo onga ayezi pansi pa malo osungunuka, kotero anhydrous acetic acid amatchedwanso glacial acetic acid.
2, asidi asidi: lili 98% glacial acetic asidi, kachulukidwe wachibale (madzi ndi 1): 1.050; Viscosity (mPa.s) : 1.22 (20 ℃); Kuthamanga kwa nthunzi pa 20 ℃ (KPa): 1.5; Maonekedwe ndi fungo: Madzi opanda mtundu okhala ndi fungo la acetic acid.
Katatu, ntchito zosiyanasiyana
1, glacial acetic acid: makamaka ntchito synthesis wa vinilu acetate, acetate CHIKWANGWANI, acetic anhydride, acetate, zitsulo acetate ndi halogenated acetic asidi. Ndiwofunikanso zopangira mankhwala, utoto, mankhwala ndi zina organic synthesis.
2, asidi asidi: angagwiritsidwe ntchito monga acidity regulator, acidifier, pickling wothandizira, flavoring wothandizira, zonunkhira, etc.
