Application of Cyanuric Acid

Synthesis of Cyanuric Acid

1. Reagents and Instruments
Cyanuric Acid, nitric acid and methanol were purchased from Beijing Chemical Plant, and the purity of the reagents were all analytical grade.
T-1200 temperature-programmed tube furnace (Hefei Kejing); HR-200 high-pressure hydrothermal reactor (Shanghai Huotong Experimental Instrument Co., Ltd.); AV400 (400 MHz) superconducting nuclear magnetic resonance instrument (NMR, Bruker, Switzerland) Company); NEXUS870 Fourier Transform Infrared Spectrometer (FTIR, Thermoelectric Nicolis, USA); Vario EL-III Elemental Analyzer (Elementar, Germany); Bruker Smart APEXIICCD Single Crystal Diffractometer (Bruker, Switzerland); JNOECXP-201 Polarizing Microscope (Shanghai Precision Instrument Co., Ltd.).
2. Experimental method
Preparation of gt-C3N4: gt-C3N4 was prepared according to the method reported in the literature. Weigh 10.0 g of Cyanuric Acid and put it in a quartz boat, then place the quartz boat in a temperature-programmed tube furnace, replace the air in the tube with N2 gas, set the heating rate at 5 °C/min under N2 gas atmosphere, and heat up To 500 °C, keep the temperature at 500 °C, and calcined for 1 h. After the calcination was completed, it was cooled to room temperature to obtain 6.2 g of yellow powder gt-C3N4 with a mass yield of 62%.
Preparation of Cyanuric Acid: Add the prepared gt-C3N4 and 1 mol/L dilute nitric acid into a hydrothermal reaction kettle at a mass ratio of 1:10, and conduct a hydrothermal reaction at 140 °C for 2 h, and wait for the reaction kettle to cool to room temperature , and the reaction solution was evaporated to dryness to obtain a white crystal product.
3. Single crystal cultivation
Take a small amount of white crystals, dissolve them in aqueous methanol (V (methanol): V (water) = 1:1), then pour the solution into a 10 mL glass bottle, seal the bottle with a small-hole sealing film, and then Place the glass bottle in a cool place to allow the solvent to evaporate slowly to obtain massive colorless transparent crystals, and select crystals of appropriate size on the stage of a polarizing microscope for single crystal diffraction testing.

Recycling Method of Cyanuric Acid

At present, in the process of synthesizing five-carbon aldehyde, the key intermediate of vitamin A, using trichloroisocyanuric acid as the chloroalcoholation reagent, trichloroisocyanuric acid produces a large amount of by-product cyanuric acid in the reaction process. Acid waste residue, its main components are Cyanuric Acid, chloroisocyanuric acid (trichloroisocyanuric acid, dichloroisocyanuric acid, monochloroisocyanuric acid), other impurities, etc. If it is not recycled, it will not only pollute the environment, but also increase the cost of the product.
Patent CN1844077A obtains powdery solid cyanuric acid by directly washing the Cyanuric Acid waste residue produced in the reaction process with water or methanol or acetone. But adopt this method to reclaim the cyanuric acid color that obtains not enough white, purity is not high, be difficult to directly reuse. CN201510970701.2 provides a method for reclaiming cyanuric acid from cyanuric acid waste residue, in order to obtain cyanuric acid with white color, high purity and direct reusability.
It includes the following operation steps: mix water and Cyanuric Acid waste residue at a liquid-solid mass ratio of 2-5:1, heat and hydrolyze at 105-155°C for 10-25 minutes; Add a decolorizing agent to the mixture, stir for 15-45 minutes and then filter; take the filtrate, cool it at 10-30°C for 3-6 hours, and then filter again to obtain crude cyanuric acid. After drying the crude cyanuric acid obtained at 80-110°C for 4-7 hours, high-purity cyanuric acid is obtained; the present invention hydrolyzes the waste cyanuric acid residue, adds a decolorizing agent for decolorization, and cools and crystallizes after filtering. , to obtain high-purity cyanuric acid products.
By hydrolyzing cyanuric acid waste residue, all chlorinated isocyanuric acid can be converted into cyanuric acid, and the obtained Cyanuric Acid product is pure white in color, and the purity and yield of Cyanuric Acid can reach 99.33% and 94.12% respectively. The hydrolysis principle of chloroisocyanuric acid in cyanuric acid waste residue is shown in the following formula.
