Abstract:Benzoguanamine is a widely used special chemical. Based on previous technology, a green synthetical route for benzoguanamine using dicyandiamide and benzonitrile as main raw material, methanol as solvent, and sodium hydroxide as catalyst was evaluated. The experimental results showed that under the optimum conditions including a reaction pressure of 0.22 MPa, a reaction temperature of 80℃, a molar ratio of dicyandiamide and benzonitrile of 1.15∶1.00, and a reaction time of 6 h, the yield of benzoguanamine can reach up to 90% with a purity of 99%. The production process is simple, clean and green, and suitable for large scale industrial production. |
Key words:benzoguanamine; dicyandiamide; benzonitrile; green production |
