This invention discloses an esterification reactor for butyl acetate reaction, comprising an esterification reactor body with an opening at the top. A cover plate is rotatably connected to a first region of the opening, and a drive box is fixed above a second region. A motor is located outside the drive box, and two coaxially nested stirring shafts are rotatably connected inside the drive box. The drive box contains a power distribution mechanism composed of a pulley set and a gear set, enabling coaxial bidirectional independent stirring of the two stirring shafts driven by a single motor. The first stirring shaft is equipped with stirring blades, and the second stirring shaft is equipped with a stirring frame with a scraper and stirring rod. The second region of the opening has a feed pipe and an exhaust pipe. This invention effectively eliminates mixing dead zones, improves mixing efficiency and reaction effect, the scraper can remove adhering substances from the reactor wall in real time, and the partitioned opening design takes into account both closed production and convenient cleaning.
