실험 절차

12.2 g of hydrazine hydrate was added to a solution of 15 g of ethyl heptanoate in 20 ml of ethanol, followed by heat-refluxing for 4.5 hours. After the reaction, the reaction mixture was cooled to precipitate a crystal. The crystal was recovered by filtration and recrystallized from 20 ml of ethanol to obtain 7 g of heptanohydrazide.
