Yield:4719-04-4 92 g

Reaction Conditions:

at 50 - 80; for 1 h;

Steps:

4 Example 4
For comparison to Example 1, in Example 4, a symmetrical triazine was made in a flask equipped with a stirrer, condenser, and temperature control device. The flask was charged with 1 Mole (31.25 gm) of 96% pure paraformaldehyde. 1 Mole (61 gm) of monoethanolamine (MEA) was added drop-wise to the flask containing the paraformaldehyde while controlling the temperature in the flask to below 50 °C. After the all the MEA wa added, the contents of the flask were stirred for 1 hour while the temperature of the flask, was maintained at 80 °C. After one hour, 92 grams of symmetrical triazine was collected. The symmetrical triazine that was produced with the above method had a freezing point of -40 °F (-40 °C).
