In a beaker dissolve 2,7g of guanidine carbonate and 1.5 g of sodium acetate in 7.5 mL of water then add 3 mL of acetylacetone with stirring. Pour the solution into an evaporating dish and heat the solution until crystalline mass starts to form, filter and wash with some water. Recrystallize from hot ethanol-water solution.
Stirring the solution
The crystalline mass is now a subject to filtration
