| description | The invention relates to a method for continuously synthesizing isoproturon by using a static mixer and a production line thereof, the method comprises the following steps: preparing a p-isopropylaniline solution, pumping the p-isopropylaniline solution into the static mixer, introducing phosgene, generating p-isopropylaniline, feeding the p-isopropylaniline solution into a thermal decomposition tower, overflowing feed liquid reaction liquid into a phosgene driving tower through a U-shaped balance pipe at the bottom, and additionally arranging an online analyzer on the U-shaped balance pipe, enabling the p-isopropyl phenyl isocyanate toluene solution qualified in light driving to pass through a static mixer, enabling synthesized isoproturon feed liquid to enter a continuous crystallization kettle, and separating and drying to obtain the isoproturon with the purity of 98.5% or above. The method provided by the invention realizes whole-course continuous generation of isoproturon, reduces the byproduct hydrochlo |
