Enantiomer self-disproportionation

Enantiomer self-disproportionation is a process in stereochemistry describing the separation of a non-racemic mixture of enantiomers in an enantioenriched fraction and a more racemic fraction as a result of the formation of heterochiral or homochiral aggregates. This process is known to occur in achiral column chromatography. The phenomenon was first recorded in 1983 introduced the term Enantiomer self-disproportionation or self-disproportionation of enantiomers. He studied achiral separations of several compounds trifloromethyl. With the help of column chromatography on normal silica gel ...


Enantiomeric excess

Enantiomeric excess is a measurement of purity used for chiral substances. It reflects the degree to which a sample contains one enantiomer in greater amounts than the other. A racemic mixture has an ee of 0%, while a single completely pure enantiomer has an ee of 100%. A sample with 70% of one enantiomer and 30% of the other has an ee of 40%.
