실험 절차

Tetrabutylphosphonium benzoate is also prepared in the following way. A solution of tetrabutylphosphonium hydroxide (4.7 g; 40% in water) is prepared. Then benzoic acid (0.8 g) is added, and the reaction solution is stirred at room temperature for 5 hours. The water is then removed in a rotary evaporator, and the residue is taken up in toluene. The toluene is removed in a rotary evaporator, and the residue is again taken up in toluene. This procedure is repeated 4-5 times. The solvent is then removed to dryness.
