WebOct 1, 1997 · The resolution of phenylsuccinic acid by salt formation with (-)-proline can be easily used as an undergraduate organic laboratory experiment. Isolation of the (+)-enantiomer can be completed in about two hours and this procedure can also be used to introduce the reflux and recrystallization techniques. WebThe observed rotation was -31.90° (the negative sign indicating a counterclockwise rotation) which calculated to a specific rotation of -33.94°.
