✦ Synopsis
The macroreticular resin XAD-2, when impregnated with benzyl or pentafluorobenzyl bromide, can effect the simultaneous extraction and derivatization of organic acids f'rom water. Reaction takes place in an aqueou+solid mixture, the derivatized products being retained on the surface of the resin, The resin is isolated by filtration and the derivatized analytes are eluted with a volatile organic solvent in the usual way. The functionalities studied were carboxylic acids, phenols and barbituric acids, The reaction conditions were developed to obtain optimal yields of the pentafluorobenzyl and benzyl derivatives. With pentalhrorobenzyl derivatives quantitative yields were obtained.
