Wopanga Mtengo Wabwino wa Glacial Acetic Acid CAS:64-19-7

1. Asidi wa acetic amapezeka mu viniga. Amapangidwa mu distillation yowononga ya nkhuni. Amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala. Amagwiritsidwa ntchito popanga cellulose acetate, acetate rayon, ndi mitundu yosiyanasiyana ya acetate ndi acetyl; ngati chosungunulira chingamu, mafuta, ndi ma resin; ngati chosungira chakudya posindikiza ndi kupaka utoto; komanso popanga zinthu zachilengedwe.
2. Asidi ya acetic ndi mankhwala ofunikira kwambiri m'mafakitale. Kachitidwe ka acetic acid ndi mankhwala okhala ndi hydroxyl, makamaka ma alcohols, kamapangitsa kuti ma acetate esters apangidwe. Kugwiritsa ntchito kwambiri acetic acid ndiko kupanga vinyl acetate. Vinyl acetate imatha kupangidwa kudzera mu kachitidwe ka acetylene ndi acetic acid. Imapangidwanso kuchokera ku ethylene ndi acetic acid. Vinyl acetate imapangidwa kukhala polyvinyl acetate (PVA), yomwe imagwiritsidwa ntchito popanga ulusi, mafilimu, zomatira, ndi utoto wa latex.
Cellulose acetate, yomwe imagwiritsidwa ntchito mu nsalu ndi filimu yojambulira zithunzi, imapangidwa pophatikizana ndi cellulose ndi acetic acid ndi acetic anhydride pamaso pa sulfuric acid. Ma esters ena a acetic acid, monga ethyl acetate ndi propyl acetate, amagwiritsidwa ntchito m'njira zosiyanasiyana.
Asidi ya Acetic imagwiritsidwa ntchito popanga pulasitiki ya polyethylene terephthalate (PET). Asidi ya Acetic imagwiritsidwa ntchito popanga mankhwala.
3. Glacial Acetic Acid ndi asidi yomwe ndi madzi owoneka bwino, opanda mtundu omwe amakhala ndi kukoma kwa asidi akasungunuka ndi madzi. Ndi oyera 99.5% kapena kupitirira apo ndipo amauma pa 17°c. Amagwiritsidwa ntchito mu saladi zosakaniza mu mawonekedwe ochepetsedwa kuti apereke acetic acid yofunikira. Amagwiritsidwa ntchito ngati chosungira, chosungunuka, komanso chokometsera. Amatchedwanso acetic acid, glacial.
4. Asidi wa acetic amagwiritsidwa ntchito ngati viniga wa patebulo, ngati chosungira komanso ngati wapakatikati mumakampani opanga mankhwala, mwachitsanzo ulusi wa acetate, ma acetates, acetonitrile, mankhwala, zonunkhira, zofewetsa, utoto (indigo) ndi zina zotero. Tsamba la Zambiri Zamalonda.
5. Imagwiritsidwa ntchito m'madzi ndi m'madzi osakhala ndi asidi.
6. Kupanga ma acetate osiyanasiyana, ma acetyl compounds, cellulose acetate, acetate rayon, mapulasitiki ndi rabara mu utoto; monga chotsukira zovala; kusindikiza calico ndi silika wopaka utoto; monga acidulant ndi chosungira zakudya; solvent ya chingamu, ma resin, mafuta ofooka ndi zinthu zina zambiri. Amagwiritsidwa ntchito kwambiri mu kupanga zinthu zachilengedwe zamalonda. Thandizo la mankhwala (acidifier).
