Reaction Steps

1.87 g of stearic acid was dissolved in 50 ml of dichloromethane, to which 0.76 g of N-hydroxysuccinimide and 1.25 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride were added and stirred at room temperature for 24 hours. After the reaction, the solution was combined with 100 ml of water and subjected to liquid-liquid separation using a separatory funnel. The organic phase obtained was dehydrated with magnesium sulfate, and enriched using an evaporator. The enriched solution was added dropwise to 20 volumes of ethanol to form a white precipitate, which was collected by filtration and dried under reduced pressure to obtain N-succinimidyl stearate.
