| titleOfInvention | Method for continuously producing tetra-substituted urea |
| abstract | A process for producing a tetra-substituted urea by reacting an amine corresponding to tetra-substitution with phosgene in the presence of an aqueous inorganic base at a temperature in the range of 0 to 150 ° C., comprising the amine, phosgene and aqueous corresponding to tetra-substitution Select the tetra-substituted urea that can be produced continuously by feeding the inorganic base to the reactor continuously in the center, the quantity ratio of the substance and substance mixture that can be fed, the temperature during the reaction and possibly the reactor Production of tetra-substituted urea, characterized by forming a two-phase system by feeding an organic solvent that cannot be completely mixed with water into it and continuously withdrawing the reaction mixture from the reactor in the middle Law. |
