| description | The present invention relates to a method for continuously manufacturing acrylic acid and a manufacturing apparatus using the same. The method for continuously manufacturing acrylic acid comprises the steps of: (1) obtaining acrylic acid-containing mixture gas by having a partial oxidization reaction of reactants including propane, oxygen, water vapor, and carbon dioxide using a catalyst; (2) separating the acrylic acid-containing mixture gas into an acrylic acid-containing solution and gaseous byproducts; (3) separating an acrylic acid solution from the separated acrylic acid-containing solution; and (4) recirculating the separated gaseous byproducts to the reactants. The continuous manufacturing method of acrylic acid in the present invention prevents excessive elevation of temperature inside a reactor while inhibiting additional generation of byproducts.
