The resolution of phenylsuccinic acid by salt formation with --proline can be easily used as an undergraduate organic laboratory experiment. Prepare a flow chart that summarizes the resolution of racemic phenylsuccinic acid. These salts will be separated by solubility in 2-propanol.

In a clean dry 250 mL round-bottomed flask dissolve 29 g of -phenylsuccinic acid in 75 mL of 2-propanol. A student performed a resolution of phenylsuccinic acid using the experimental procedure that is described in the handout. Isolation of the -enantiomer has been successfully completed in our undergraduate organic laboratory for the past four years by more than 1500 students.

You will determine the efficiency of the resolution by determining the specific rotation of the two enantiomers. Include a full arrowpushing mechanism in your discussion to illustrate. Describe the resolution of racemic phenylsuccinic acid using Sproline to isolate Sphenylsuccinic acid.

Empirical Formula Hill Notation. CHEMICAL RESOLUTION OF -PHENYLSUCCINIC ACID WITH --PROLINE. An Introductory Organic Chemistry Experiment.

These diastereoisomers can easily be separated because they possess different physical properties. Describe the point in the experimental procedure at which the two enantiomers of phenylsuccinic acid were separated from each other when the racemic mixture is mixed with isopropanol and L-proline and heated at reflux for 30 min the cooled the solution is then filtered to collect the PSA which precipitates out and the separation is made. The polarimeter cell had a length that was measured to be 100 cm.
