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 ndi yosavuta carboxylic acid ndi reagent yofunika mankhwala.Elebrium imagwiritsidwanso ntchito popanga polyethoethyls mu acetate ndi polyetate mu zomatira mufilimu ya filimuyi, komanso ulusi wambiri wopangidwa ndi nsalu.Amagwiritsidwa ntchito popanga zinthu monga ethyl acetate, acetate, acetate, ndi chlorine -album acid.Ndikofunikira kwambiri pakupangira ulusi wopangira, zomatira, mankhwala, mankhwala ophera tizilombo ndi utoto.Ndiwosungunulira bwino kwambiri.Imakhalanso yotchuka kwambiri m'makampani.
Acetic acid angagwiritsidwe ntchito ngati owongolera acidic, acidification agents, pickles, flavor add agents, zonunkhira, ndi zina zotero. Ndi bwinonso anti-microbiological agent, yomwe makamaka chifukwa chake imatha kuchepetsa pH ya pH ku ** tizilombo toyambitsa matenda.
Asidi acetic ndi ntchito m'mbuyomu ndipo ntchito m'dziko langa, amene makamaka ntchito zokometsera gulu, chilinganizo, zamzitini, tchizi, odzola, etc. Mukagwiritsidwa ntchito zokometsera, mukhoza kuchepetsa madzi 4% mpaka 5% yankho, ndi kuwonjezera. izo ku zokometsera zosiyanasiyana.Zakumwa zopangidwa ndi viniga ngati zokometsera zowawa, zowonjezeredwa ndi zinthu zopatsa thanzi * zopatsa thanzi zimatchedwa *mtundu * mibadwo itatu ya zakumwa.
Wonjezerani zambiri:
Kukonzekera acetic acid: Iwo akhoza pamodzi ndi kaphatikizidwe Buku ndi bakiteriya nayonso mphamvu.The biological synthesis njira, ndiko kuti, kugwiritsa ntchito mabakiteriya nayonso mphamvu, imangotenga 10% ya dziko lonse lapansi, koma ikadali njira yofunika kwambiri popangira acetic acid, makamaka vinyo wosasa, chifukwa malamulo oteteza chakudya m'malo ambiri amanenera. kuti viniga mu chakudya ndi kudzera mu biology.Dongosolo lazamalamulo, ndi njira yowotchera imagawidwa mu njira yowotchera ya aerobic ndi njira yowotchera ya anaerobic.
Pankhani ya okosijeni wambiri, mabakiteriya a viniga amatha kupanga asidi kuchokera ku zakudya zomwe zili ndi mowa.Nthawi zambiri mugwiritseni ntchito vinyo wa apulo kapena vinyo wosakaniza njere, malt, mpunga kapena mbatata kuti mufufuze.Ma chemical equation omwe amayatsidwa ndi mabakiteriyawa ndi awa:
C?HOH + O?→ CHA?COOH + H?O
Mamembala ena a mabakiteriya a anaerobic, kuphatikizapo ena amtundu wa Ritula, amatha kusintha shuga kukhala ethanol popanda kufunikira ethanol ngati apakatikati.
