Abstract

La presente invencion se refiere a un procedimiento para producir un aldehídoopticamente activo (primer aldehído) que contiene una cantidad reducida del aldehído enantiomérico correspondiente (segundo aldehído), dicho procedimiento comprende: (1) suministrar una solucion inicial que contiene una mezcla no eutéctica del primer aldehído y del segundo aldehído, dicha mezcla tiene una composicion en la region composicional donde solamente el primer aldehído se cristaliza cuando se rebasa su límite de solubilidad en la solucion, y (2) mantener la solucion a una temperatura superior a la temperatura eutéctica de la mezcla y bajo condiciones tales que el límite de solubilidad del primer aldehído se rebasa para formar un primer aldehído cristalino que contiene una proporcion relativamente menor del segundo aldehído en comparacion con la cantidad presente en la solucion inicial.
