Acetic acid, ulwelo olungenambala, lunevumba elibukhali elibukhali.Indawo yokunyibilika ye-acetic acid yi-16.6 ℃, indawo yokubilisa yi-117.9 ℃, ingxinano ye-1.0492 (20/4 ℃), kunye ne-refractive index yi-1.3716.Iasidi yeacetic enyulu inokwenza isiqina esifana nomkhenkce ngaphantsi kwe-16.6 °C, ngoko ihlala ibizwa ngokuba yi-glacial acetic acid.I-acetic acid yinto ebalulekileyo ye-organic organic material ekrwada, esetyenziselwa kakhulu ukulungiselela i-vinyl acetate monomer (VAM), i-cellulose acetate, i-acetic anhydride, i-terephthalic acid, i-chloroacetic acid, i-polyvinyl alcohol, i-acetate kunye ne-acetate yensimbi.
I-acetic acid isetyenziswa ngokubanzi kwisiseko se-organic synthesis, amayeza, amayeza okubulala izitshabalalisi, ukuprinta kunye nokudaya, amalaphu, ukutya, ipeyinti, izinto zokuncamathelisa kunye namanye amashishini amaninzi.I-acetic acid yimathiriyeli ebalulekileyo yekhemikhali ekrwada.Ubuchwephesha bemveliso ye-acetic acid ikakhulu bubandakanya: indlela ye-methanol carbonylation, i-acetaldehyde oxidation, i-ethylene ngqo oxidation kunye ne-oxidation yeoli elula.Phakathi kwabo, i-methanol carbonylation yeyona teknoloji isetyenziswa kakhulu, ibalwa ngaphezu kwe-60% yezinga elipheleleyo lemveliso yehlabathi, kwaye lo mkhwa usakhula.
Umthamo wemveliso yeasidi yehlabathi jikelele ubonise ukunyuka, kwaye imfuno yayo yehlabathi nayo iya kukhula ngomyinge wonyaka omalunga ne-5% kwiminyaka embalwa ezayo, apho i-94% yomthamo omtsha wehlabathi we-acetic acid iya kwenzeka. I-Asiya, kunye nommandla wase-Asiya kuya kubakho kwixesha elizayo.Ukukhokela ukukhula okukhawulezayo kwemfuno yentengiso yehlabathi kwisithuba seminyaka emihlanu.
isicelo:
1. I-acetic acid derivatives: isetyenziswa kakhulu kwi-synthesis ye-acetic anhydride, i-acetate, i-terephthalic acid, i-vinyl acetate / i-polyvinyl alcohol, i-cellulose acetate, i-ketene, i-chloroacetic acid, i-haloacetic acid, njl.;
2. Iyeza: I-Acetic acid isetyenziswa njenge-solvent kunye ne-pharmaceutical material ekrwada, esetyenziswa kakhulu kwimveliso ye-penicillin G potassium, i-penicillin G ye-sodium, i-procaine penicillin, i-antipyretic tablets, i-sulfadiazine, i-sulfamethoxazole, i-norfloxacin, i-ciprofloxacin Floxacin, i-acetylsalicylic acid, i-acetylsalicylic acid. i-prednisone, i-caffeine, njl.;
3. Abaphakathi abahlukeneyo: i-acetate, i-sodium diacetate, i-peracetic acid, njl.;
4. Ii-pigments kunye ne-textile printing kunye nokudaya: ikakhulu isetyenziselwa ukuveliswa kweedayi ezisasazwayo kunye nedayi ye-vat, kunye nokuprintwa kwe-textile kunye nokulungiswa kokudaya;
5. I-ammonia ye-Synthetic: ngendlela ye-cupric acetate ammonia liquid, isetyenziselwa ukucocwa kwegesi ye-synthesis ukususa inani elincinci le-CO kunye ne-CO2 equlethwe kuyo;
6. Kwisithombe: ukuqulunqwa njengomphuhlisi;
7. Ngokubhekiselele kwirubha yendalo: isetyenziswe njenge-coagulant;
8. Kwishishini lokwakha: lisetyenziswa njenge-anticoagulant.
