1.25 g of neodymium(III) nitrate hexahydrate in 7 mL of aq. 95% ethanol is placed in a reflux apparatus, whereto 1 mL of acetylacetone is added and the solution is brought to a gentle reflux for 30 minutes. The solution is combined with 1.5 g of sodium acetate trihydrate dissolved in 8 mL of water and it is heated to 70°C for 20 minutes. The mixture is placed in a refrigerator until cold, filtered and washed with a little cold water. The product is obtained as a hydrate and it is left to dry in open air.
3 C5H8O2 + Nd(NO3)3 · 3H2O = Nd(C5H7O2)3 · xH2O + 3 HNO3
C5H7NaO2 + HNO3 = NaNO3 + C5H8O2
