YieldReaction ConditionsOperation in experiment
With formic acid; In N,N-dimethyl-formamide; at 20℃; for 8h;Reflux; 1) 1mol melamine was weighed and dissolved in 60ml of DMF. The system was raised to 120C to completely dissolve under stirring. 2) 2mol <strong>[110677-45-7]4-(carbazol-9-yl)benzaldehyde</strong> was weighed and dissolved in 20ml of DMF at room temperature with stirring. 3) The solution obtained in step 2 was added dropwise to the step 1 solution. 0.01mol formic acid was added and refluxed for 8h. The reaction was completed. The final reaction product was removed of solvent by rotary evaporation and purified by column chromatography to isolate pure melamine polycondensated with carbazolbenzaldehyde double Schiff base.
