Acetic acidndi yofunika kwambiri organic mankhwala zopangira, chimagwiritsidwa ntchito m'mafakitale ambiri. M'mafakitale ambiri omwe amagwiritsa ntchito acetic acid, makampani oyeretsedwa a terephthalic acid (PTA) amadya acetic acid.
Mu 2023, PTA ikhala ndi gawo lalikulu kwambiri pagawo la acetic acid. PTA imagwiritsidwa ntchito kwambiri popanga zinthu za poliyesitala, monga mabotolo a polyethylene terephthalate (PET), filimu ya poliyesitala ndi filimu ya poliyesitala, yomwe imagwiritsidwa ntchito kwambiri popanga nsalu, ma CD ndi zina.
Kuphatikiza apo, asidi acetic amagwiritsidwanso ntchito popanga ethylene acetate, acetate (monga ethyl acetate, butyl acetate, etc.), acetic anhydride, chloroacetic acid ndi mankhwala ena, komanso amagwiritsidwa ntchito ngati chosungunulira mu mankhwala ophera tizilombo, mankhwala ndi mankhwala. utoto ndi mafakitale ena. Mwachitsanzo, vinyl acetate amagwiritsidwa ntchito popanga zokutira zoteteza, zomatira, ndi mapulasitiki; Acetate ikhoza kugwiritsidwa ntchito ngati zosungunulira; Acetic anhydride amagwiritsidwa ntchito popanga acetate fiber, mankhwala, utoto, etc. Chloroacetic acid imagwiritsidwa ntchito popanga mankhwala ophera tizilombo, mankhwala, utoto ndi zina zotero.
Nthawi zambiri,asidi asidiali ndi ntchito zofunika m'mafakitale ambiri monga makampani opanga mankhwala, ulusi wopangira, mankhwala, mphira, zowonjezera chakudya, utoto ndi kuluka. Ndi chitukuko cha mafakitale osiyanasiyana, malo ogwiritsira ntchito angapitirize kukula.
