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 zozizirirapo mpweya wokwanira.
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 kuteteza / 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, acetinanisolic acid, prefloxacin, acetinasolic acid, acetinal, acetinal, sulfadiazine. , 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 mapulogalamu
7. Labala lachilengedwe: Coagulant
8. Makampani omanga: Kupewa konkire ku frezing9.Mu addtin amagwiritsidwanso ntchito kwambiri pochiza madzi, syntheticfiber, mankhwala ophera tizilombo, mapulasitiki, zikopa, utoto, kukonza zitsulo ndimakampani amphira.
Acetic acid (yomwe imatchedwanso acetic acid, glacial acetic acid, kapena formula CH COOH) ndi organic mono acid yomwe ₃ ndiye gwero la acidity ndi fungo loyipa la viniga.Pure anhydrous acetic acid (glacial acetic acid) ndi madzi opanda mtundu a hygroscopic okhala ndi kuzizira kwa 16.7 ° C (62 ° F) ndipo amakhala kristalo wopanda mtundu akakhazikika.Ngakhale acetic acid ndi asidi wofooka chifukwa cha mphamvu yake yolekanitsa muzitsulo zamadzimadzi, acetic acid ndi yowononga ndipo nthunzi yake imakwiyitsa maso ndi mphuno.
