Pengfa Chemical-Katswiri Wopanga Acetic Acid

      Acetic acid, madzi opanda mtundu, ali ndi fungo lamphamvu.Acetic acid yomwe imasungunuka ndi 16.6 ℃, malo owira ndi 117.9 ℃, kachulukidwe kake ndi 1.0492 (20/4 ℃), ndipo refractive index ndi 1.3716.Acetic acid yoyera imatha kupanga olimba ngati ayezi pansi pa 16.6 °C, motero nthawi zambiri amatchedwa glacial acetic acid.Acetic acid ndi yofunika organic mankhwala zopangira, makamaka ntchito pokonzekera vinyl acetate monomer (VAM), cellulose acetate, acetic anhydride, terephthalic acid, chloroacetic acid, polyvinyl mowa, acetate ndi zitsulo acetate.

Acetic acid chimagwiritsidwa ntchito mu organic synthesis, mankhwala, mankhwala, kusindikiza ndi utoto, nsalu, chakudya, utoto, zomatira ndi mafakitale ena ambiri.Acetic acid ndi chinthu chofunikira kwambiri chopangira mankhwala.Tekinoloje zopanga mafakitale za asidi acetic makamaka zimaphatikizapo: njira ya methanol carbonylation, acetaldehyde oxidation, ethylene direct oxidation ndi light oil oxidation.Pakati pawo, methanol carbonylation ndi teknoloji yomwe imagwiritsidwa ntchito kwambiri, yomwe imakhala yoposa 60% ya mphamvu zonse zapadziko lonse lapansi, ndipo izi zikukulabe.

Kuchulukirachulukira kwa acetic acid padziko lonse lapansi kwakhala kukukulirakulira, ndipo kufunika kwake padziko lonse lapansi kudzakulanso pafupifupi 5% pachaka mzaka zingapo zikubwerazi, pomwe 94% ya mphamvu yatsopano yopangira asidi padziko lonse lapansi idzachitika Asia, ndi dera la Asia lidzakhalanso mtsogolo.Kutsogolera kukula kwachangu kwa msika wapadziko lonse lapansi pazaka zisanu.

ntchito:
1. Acetic acid zotumphukira: makamaka ntchito synthesis acetic anhydride, acetate, asidi terephthalic, vinilu acetate/polyvinyl mowa, mapadi acetate, ketene, chloroacetic asidi, asidi haloacetic, etc.;
2. Medicine: Acetic asidi ntchito monga zosungunulira ndi mankhwala zopangira, makamaka ntchito kupanga penicillin G potaziyamu, penicillin G sodium, procaine penicillin, antipyretic mapiritsi, sulfadiazine, sulfamethoxazole, norfloxacin, ciprofloxacin Floxacin, acetylsalicylic acid, phenolsalicylic acid, prednisone, caffeine, etc.;
3. Zosiyanasiyana zapakati: acetate, sodium diacetate, peracetic acid, etc.;
4. Nkhumba ndi nsalu zosindikizira ndi zopaka utoto: zomwe zimagwiritsidwa ntchito makamaka popanga utoto wobalalitsa ndi utoto wa vat, komanso kusindikiza nsalu ndi kukonza utoto;
5. Synthetic ammonia: mu mawonekedwe a cupric acetate ammonia madzi, amagwiritsidwa ntchito monga kuyengedwa kwa kaphatikizidwe gasi kuchotsa pang'ono CO ndi CO2 zomwe zili mmenemo;
6. Pachithunzichi: kupangidwa monga wopanga;
7. Pankhani ya mphira wachilengedwe: amagwiritsidwa ntchito ngati coagulant;
8. M'makampani omangamanga: amagwiritsidwa ntchito ngati anticoagulant.
