I-Pengfa Chemical—Umkhiqizi Ochwepheshe we-Acetic Acid

      I-acetic acid, uketshezi olungenambala, lunephunga elinamandla.Iphuzu elincibilikayo le-acetic acid ngu-16.6 ℃, indawo yokubilisa ngu-117.9 ℃, ukuminyana okuhlobene ngu-1.0492 (20/4 ℃), kanti inkomba ye-refractive ingu-1.3716.I-acetic acid ehlanzekile ingakha okuqinile okufana neqhwa ngaphansi kuka-16.6 °C, ngakho-ke kuvame ukubizwa nge-glacial acetic acid.I-acetic acid iyi-organic chemical material eluhlaza, ikakhulukazi esetshenziselwa ukulungisa i-vinyl acetate monomer (VAM), i-cellulose acetate, i-acetic anhydride, i-terephthalic acid, i-chloroacetic acid, i-polyvinyl alcohol, i-acetate ne-acetate yensimbi.

I-acetic acid isetshenziswa kabanzi ku-organic synthesis eyisisekelo, imithi, izibulala-zinambuzane, ukuphrinta nokudaya, izindwangu, ukudla, upende, izinto zokunamathisela nezinye izimboni eziningi.I-acetic acid iyimpahla eluhlaza yamakhemikhali ebalulekile.Ubuchwepheshe bokukhiqiza obuthuthukisiwe be-acetic acid ikakhulukazi buhlanganisa: indlela ye-methanol carbonylation, i-acetaldehyde oxidation, i-ethylene oxidation eqondile kanye ne-oxidation kawoyela okhanyayo.Phakathi kwazo, i-methanol carbonylation iwubuchwepheshe obusetshenziswa kakhulu, obungaphezu kuka-60% yenani eliphelele lokukhiqiza emhlabeni wonke, futhi lo mkhuba usakhula.

Umthamo wokukhiqiza i-acetic acid emhlabeni wonke ubulokhu ukhombisa ukukhuphuka, futhi isidingo sawo emhlabeni wonke sizokhula ngesilinganiso sonyaka esingaba ngu-5% eminyakeni embalwa ezayo, lapho u-94% wawo amandla okukhiqiza i-acetic entsha emhlabeni wonke azokwenzeka I-Asia, kanye nesifunda sase-Asia nazo zizoba khona esikhathini esizayo.Okuholela ekukhuleni okusheshayo kwesidingo sezimakethe zomhlaba phakathi neminyaka emihlanu.

isicelo:
1. I-acetic acid derivatives: isetshenziswa ikakhulukazi ekuhlanganiseni kwe-acetic anhydride, i-acetate, i-terephthalic acid, i-vinyl acetate/i-polyvinyl alcohol, i-cellulose acetate, i-ketene, i-chloroacetic acid, i-haloacetic acid, njll.;
2. Umuthi: I-acetic acid isetshenziswa njenge-solvent kanye nemithi eluhlaza, ikakhulukazi esetshenziswa ekukhiqizeni i-penicillin G potassium, i-penicillin G sodium, i-procaine penicillin, amaphilisi e-antipyretic, i-sulfadiazine, i-sulfamethoxazole, i-norfloxacin, i-ciprofloxacin Floxacin, i-acetylsalicylic acid, i-acetylsalicylic acid, i-prednisone, i-caffeine, njll.;
3. Izikhala ezihlukahlukene: i-acetate, i-sodium diacetate, i-peracetic acid, njll;
4. Ama-pigments kanye ne-textile ukuphrinta nokudaya: ikakhulukazi esetshenziselwa ukukhiqizwa kwamadayi ahlakazayo namadayi e-vat, kanye nokuphrinta kwendwangu kanye nokucubungula ukudaya;
5. I-ammonia yokwenziwa: ngendlela ye-cupric acetate ammonia liquid, isetshenziswa njengokucwengisiswa kwegesi yokwenziwa ukuze kukhishwe inani elincane le-CO ne-CO2 equkethwe kuyo;
6. Esithombeni: ukwakhiwa njengonjiniyela;
7. Ngokwenjoloba yemvelo: esetshenziswa njenge-coagulant;
8. Embonini yezokwakha: isetshenziswa njenge-anticoagulant.
