Abstract: A novel chiral extractant n-octyl-L-hydroxyproline was synthesized. The extraction mechanism and property of D- or L-phenyl alanine with n-octyl-L-hydroxyproline with n-octane and n-octanol(volume ratio, 7∶3) as the diluent was investigated. The effect of concentrations of extractant and copper ion and pH on the extraction of phenyl alanine was studied. The influence of temperature on the extraction shows that the extraction is endothermic reaction. The extracted species were characterized and the structure was suggested. This result will be helpful for the further study on extracting and separating D,L-phenyl alanine.

Key words: n-Octyl-L-hydroxyproline, Extraction, Phenyl alanine
