Procedure

In a suitable 2 L reactor, maintained under nitrogen atmosphere, 50 g (305 mmol) of straight hydrated TETA and 1 L of absolute ethanol are loaded. To the solution 44.5 g (305 mmol) of a 40% glyoxal solution are added. After completion of the addition, the solution is kept under magnetic stirring at 23° C. for 17 hours. The resulting solution is concentrated under partial vacuum to an oily residue.
