General procedure for the synthesis of hydroxyethyl hexahydrohomotriazine from formaldehyde and 2-aminoethanol: To 6.1 g (0.1 mol) of 2-aminoethanol was added 3.0 g (0.1 mol as formaldehyde) of a 20 mL methanol solution of paraformaldehyde, and the mixture was stirred for 48 h at room temperature. Upon completion of the reaction, the solvent was removed by rotary evaporator and the residue was distilled under reduced pressure to give 6.3 g (86% yield) of light yellow viscous liquid. The physicochemical properties of the obtained compound (I) were in accordance with the data reported in literature [9].
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).
