실험 절차

1 mol of phosphoric acid diethyl ester chloride and 1.07 mols of 50% strength sodium hydroxide solution were added dropwise to 3.33 mols of propargyl alcohol (233% excess) at 15°-20° C. The mixture was stirred for 15 minutes, water was added to dissolve the salt and the mixture was extracted with 800 ml of chloroform. On distillation, 70% of phosphoric acid diethyl propargyl ester was obtained.
