Acid aciddareere aan midab lahayn, wuxuu leeyahay ur daran.Barta dhalaalka ee acetic acid waa 16.6 ℃, barta karkarinta waa 117.9 ℃, cufnaanta qaraabada waa 1.0492 (20/4 ℃), iyo index refractive waa 1.3716.Ashitada saafiga ah ee loo yaqaan 'acetic acid' waxay sameyn kartaa baraf u eg oo ka hooseeya 16.6 °C, sidaas darteed waxaa badanaa loo yaqaan 'glacial acetic acid'.Acetic acid waa walxo kiimiko ah oo muhiim ah oo ceeriin ah, oo inta badan loo isticmaalo diyaarinta vinyl acetate monomer (VAM), acetate cellulose, acetic anhydride, terephthalic acid, chloroacetic acid, alkohol polyvinyl, acetate iyo birta acetate.
Acetic acid waxaa si weyn loogu isticmaalaa isku-dhafka dabiiciga ah ee aasaasiga ah, daawada, sunta cayayaanka, daabacaadda iyo midabaynta, dharka, cuntada, rinjiga, dhejiska iyo warshado kale oo badan.Acid acid waa walxo kiimiko ah oo ceeriin ah oo muhiim ah.Farsamooyinka wax soo saarka warshadaha ee acetic acid inta badan waxaa ka mid ah: Habka carbonylation methanol, oxidation acetaldehyde, oksaydhka tooska ah ee ethylene iyo oksaydhka saliidda fudud.Waxaa ka mid ah, methanol carbonylation waa tignoolajiyada ugu isticmaalka badan, taas oo ka dhigan in ka badan 60% wadarta guud ee awoodda wax soo saarka caalamiga ah, isbeddelkani weli wuu sii kordhayaa.
Awoodda wax-soo-saarka acetic acid ee caalamiga ah waxay muujinaysay kor u kac, iyo baahideeda caalamiga ah waxay sidoo kale kori doontaa celcelis ahaan heerka sanadlaha ah ee ku saabsan 5% dhowrka sano ee soo socda, taas oo 94% ee awoodda wax soo saarka cusub ee acetic acid ay dhici doonto Aasiya, iyo gobolka Aasiya ayaa sidoo kale noqon doona mustaqbalka.Hoggaaminta kobaca degdega ah ee baahida suuqa adduunka shan sano gudahood.
