| description | The invention discloses a thermo-optic technical method for compounding isocyanate products. A thermo-optic technology comprises an electro luminescence technology of introducing in a small amount ofinert gas for protecting, removing water by serially connecting a water knockout trap and collecting a phosgene-containing solvent for standby use, and a rectifying technology of carrying out hot filtration on a thermo-optic reaction solution for standby use. The thermo-optic technical method disclosed by the invention can be widely applied to technological operation of preparing the isocyanate products by adopting a phosgene method and can be particularly applied to a thermo-optic technology of 3,5-dichlorophenyl isocyanate, so that solid residue generated during reaction is reduced, the amount of three wastes is small, the yield of the products is increased, and high quality of the products is ensured. The invention also discloses a treating device of the reaction solution in the thermo-optic technical method fo |
