A racemic mixture is one that contains equal amounts of both enantiomers, which has an overall optical activity of 01 the purpose of this experiment is to obtain pure enantiomers from their racemic mixture by treating the racemic mixture with a dissymmetric acid and obtaining diastereomeric salts. The mixture was composed of the undermentioned substances 55g sand 24g fe fillings 25ml methylated liquors 13g of nacl 06 g of na sulfhate 13ml of hexane the purpose of this experiment was to divide a mixture back into its original constituents based on the mixtures physical and chemical constituents.
The pure amine yield out of the initial racemic mixture was calculated to be 4106% that result indicated that the purification was fairly successful because the racemic mixture contains equal amounts of the both enantiomers and therefore the most yield that can be obtained of one particular enantiomer is only 50.
Introduction in this experiment, a racemic mixture was resolved into its enantiomer by separation of its diastereomeric derivative this is a common procedure in organic chemistry that has been found to be useful and is simpler the racemic mixture used in this experiment was (+)-α-phenylethylamine this racemic mixture was treated with a pure resolving agent, tartaric acid, which resulted in. ( ± ) --phenylethylamine is a racemic mixture and contains both enantiomorphs in equal measures the diastereomers that are produced due to the declaration are salts that are either ( + ) ( + ) or ( + ) ( – ) as the acid is ( + ) and the enantiomorphs are either ( + ) or ( – ). Among the different techniques for separation of enantiomers, diastereoisomeric crystallization with different basis (r-(+)-phenylethylamine, n-methyl-d-glucamine) has been the dominant one in the pharmaceutical industry for the resolution of ibuprofen [5,6.
