实验过程

Dissolve 10 mmol palmityl toluene-4-sulfonate, 10 mmol ethyl 12-hydroxystearate, 10 mmol anhydrous potassium carbonate and 0.5 mmol sodium iodide in 100 ml dry acetonitrile and heat to 81° C. with stirring for 6 hours. The reaction is cooled to room temperature. The solvent is evaporated and the products are suspended in MTBE and washed with 3×50 ml cold water. The solvent is evaporated to yield ethyl 12-palmityloxy-stearate.
