PROBLEM TO BE SOLVED: To provide an efficient method for removing by-produced dibutyl ether in order to, in a production process of butyl acrylate, mitigate restrictions on an esterification reaction and a heat decomposition reaction, which are for suppressing by-production of dibutyl ether. ! SOLUTION: Provided is a method for continuously producing butyl acrylate, comprising: an esterification reaction step of obtaining a reaction mixture by an esterification reaction of acrylic acid and butanol in a reactor in the presence of an acid catalyst, and continuously separating the reaction mixture under reduced pressure into crude butyl acrylate and a volatile component; a distillation step of distilling the volatile component in a reactive distillation column, returning a discharge component to the reactor, separating a distillate component into an organic layer and an aqueous layer, and circulating the organic layer into the reactive distillation column; and a purification step of obtaining butyl acrylate |
