2,4,6-TRIOXO-1,3,5-TRIAZINE-1,3,5(2H,4H,6H)-TRIPROPIONITRILE synthesis

Yield:2904-28-1 95.76%

Reaction Conditions:

with tetrabutylammomium bromide in n-heptane at 95 - 100; for 9 h;

Steps:

1-5 Example 1

In a 250mL four-necked flask equipped with a thermometer, add 55g n-heptane, 12.9g cyanuric acid, 20.1g acrylonitrile, 1.8g tetrabutylammonium bromide, install the condenser, start the stirrer, and heat up to 95- At 110°C, the condensation reaction time was 9h (using liquid chromatography to monitor the reaction). After the reaction, add 50g of hot water at 75°C to wash, separate the water phase, and then wash with 50g water once, separate the water phase, remove the water from the organic phase, and decolorize the organic phase with activated carbon. Cool the organic phase to 8-10°C, complete the crystallization, and filter. , The curing agent intermediate N,N,N-tris(3'-cyanopropyl)-1,3,5-triazine product is obtained, and the product yield is 95.76%.
