Kodi glacial acetic acid ndi chiyani?
Glacial Acetic Acid, glacial acetic acid zochita, Opanga glacial acetic acid, glacial asidi acetic ntchito ndi zotsatira,

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.
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.
acetic acid, saturated carboxylic acid yomwe ili ndi ma atomu awiri a carbon, ndi yofunika kwambiri yomwe imakhala ndi oxy kuchokera ku ma hydrocarbon. Mapangidwe a mamolekyu C2H4O₂, kapangidwe ka maselo
Mapangidwe a maselo
Chofupikitsa CH₃COOH, HAC ndiye mawonekedwe achidule. Gulu logwira ntchito la chilinganizo chokhazikika ndi gulu la carboxyl ndi nambala ya CAS ndi 64-19-7. Chifukwa ndicho chigawo chachikulu cha viniga, chomwe chimatchedwanso asidi. Mu zipatso kapena mafuta a masamba, mwachitsanzo, makamaka mu mawonekedwe a esters a mankhwala awo; Imapezeka ngati asidi waulere m'matumbo, ndowe, ndi magazi a nyama. Viniga wamba ali ndi 3% mpaka 5% asidi acid. Acetic acid ndi madzi opanda mtundu komanso fungo lamphamvu. Kulemera kwa maselo ndi 60.05, malo osungunuka ndi 16.6 ℃, malo otentha ndi 117.9 ℃, kachulukidwe kake ndi 1.0492 (20/4 ℃), kachulukidwe ndipamwamba kuposa madzi, index refractive ndi 1.3716. Acetic acid yoyera imatha kupanga olimba ngati ayezi pansi pa 16.6 ° C, motero nthawi zambiri amatchedwa glacial acetic acid. Kusungunuka m'madzi, ethanol, ether ndi carbon tetrachloride. Madzi akawonjezeredwa ku asidi acetic, voliyumu yonseyo imakhala yaying'ono ndipo kachulukidwe kake kamawonjezeka mpaka kuchuluka kwa mamolekyulu ndi 1: 1, zomwe zimagwirizana ndi mapangidwe a mono-acid CH3C (OH) ₃, omwe amachepetsedwanso ndipo sasinthanso kuchuluka kwake. .
