الإجراء التجريبي

After the completion of the reaction, an extractant such as ethyl acetate is added to the reaction mixture which separates the reaction mixture into an upper layer and a lower layer. The upper layer contains D-HPAE in ethyl acetate and the lower layer contains L-HPA in water. After separating the lower layer from the upper layer, the extractant, i.e., ethyl acetate, can be vaporized to obtain D-HPAE, which can be chemically hydrolyzed to obtain D-homophenylalanine. L-HPA can be separated from the lower layer by adjusting its solution pH to about 6.3 to cause the precipitation thereof.
