실험 절차

To a solution of 0.49 g (3.6 mmol) of 4-methylpicolinic acid dissolved in 2.5 ml of water, a solution of 0.40 g (1.8 mmol) of zinc acetate.dihydrate dissolved in 1.5 ml of water was dropwise added while stirring. After the dropwise addition, the mixture was stirred at room temperature for one hour. Because no solid was precipitated, the mixture was evaporated to dryness under a reduced pressure, and the solid obtained was washed with acetone under heating to give 0.50 g of the desired zinc salt. No recrystallization was possible from either water or ethanol (yield 79.1%).
