    摘要: A method for the chromatographic resolution and analysis of the enantiomers of 2-(phenyl or phenoxy)propionic acids or the C.sub.1 -C.sub.4 alkyl esters thereof which comprises converting a racemic or partially resolved mixture of said 2-(phenyl or phenoxy)propionic acids or the C.sub.1 -C.sub.4 alkyl esters thereof to a pair of diastereomeric 2-amino-1-alkanol derivatives by reaction with an optically active 2-amino-1-alkanol, and analyzing the diastereomeric mixture by gas chromatography.
