Abstract

ESTA INVENCION SE RELACIONA CON UN PROCESO PARA PRODUCCION DE UN ALDEHIDO OPTICAMENTE ACTIVO (PRI- MER ALDEHIDO) QUE CONTIENE UNA CANTIDAD REDUCIDA DEL ALDEHIDO ENANTIOMERICO CORRESPONDIENTE (SEGUN- DO ALDEHIDO), EL PROCESO COMPRENDE: (1) SUMINISTRO DE UNA SOLUCION INICIAL QUE CON- TIENE UNA MEZCLA NO EUTECTICA DEL PRIMER ALDEHIDO Y EL SEGUNDO ALDEHIDO, TAL MEZCLA TIENE UNA COMPO- SICION EN LA REGION DE CONFORMACION DONDE SOLAMEN- TE EL PRIMER ALDEHIDO SE CRISTALIZA CUANDO SU LI- MITE DE SOLUBILIDAD EN LA SOLUCION ES EXCEDIDO, Y (2) MANTENIMIENTO DE LA SOLUCION A UNA TEMPERATU- RA POR ENCIMA DE LA TEMPERATURA EUTECTICA DE LA MEZCLA Y BAJO CONDICIONES TALES QUE EL LIMITE DE SOLUBILIDAD DEL PRIMER ALDEHIDO ES EXCEDIDO PARA FORMAR UN PRIMER ALDEHIDO CRISTALINO QUE CONTENGA RELATIVAMENTE MENOS DEL SEGUNDO ALDEHIDO QUE LO QUE ESTUVO PRESENTE EN LA SOLUCION INICIAL.
