| 摘要 |
The present invention discloses a process for the preparation of Anilazine, wherein it can be obtained from a reaction between Cyanuryl Chloride with Ortochloraniline in a 1:1 molar ratio, due to the possibility of a successive chloride atom exchange as a temperature function. Cyanuryl chloride can be converted to anilazine substituting only one of its chloride atoms by ortochloraniline, wherein chloride reacts in the direction of a nucleophilic substitution. It is relevant to control variations in the reaction conditions and reaction media for the synthesis of this product. This was studied by working on the product synthesis in laboratory tests, in a test plant and the product plant production. The synthesis process is performed using water as reaction media and controlling the temperature variation resulting from the reaction, by modifying the reaction media to reactives ratio. An appropriate control of this reaction media to reactive ratio allows to obtain a yield over 90 percent of product.
