Abstract:

A simple and efficient synthesis of cyanuric acid by thermal polymerization and hydrothermal treatment was developed using melamine as the raw material. The product structure was characterized by X-ray single crystal diffraction, nuclear magnetic resonance (NMR), Fourier transform infrared spectrometry (FTIR), mass spectrometry and elemental analysis. Under the optimal hydrothermal reaction temperature of 140 ℃, the reaction was carried out for 2 h, and the total yield was up to 54%. The synthesis method is simple and has less pollution, providing a new reference method for industrial preparation of cyanuric acid.

Key words: cyanuric acid, hydrothermal method, structural analysis
