Abstract
UN PROCESO PARA OBTENER UN ISOMERO DE UN COMPONENTE DE LA FORMULA GENERAL (I): R-CH(CN)-R , EN DONDE CADA UNO DE LOS R Y R DEBEN SER CUALQUIER RADICAL ORGANICO ENLAZADO DIRECTAMENTE O A TRAVES DE UN HETEROATOMO AL ATOMO DE CARBONO QUE LLEVA EL GRUPO CIANO PROVISTO QUE AL MENOS UNO DE R Y R COMPRENDA AL MENOS UN CENTRO QUIRAL RESUELTO QUE ES ESTABLE BAJO LAS CONDICIONES DEL PROCESO, O UNA MODIFICACION RACEMICA QUE COMPRENDE AL ISOMERO Y SU ENANTIOMERO, QUE COMPRENDE EL PASO DE TRATAR EL EPIMERO DEL ISOMERO, O EL RACEMATO QUE COMPRENDE EL EPIMERO Y EL ENANTIOMERO DEL EPIMERO, EN LA SOLUCION EN UN SOLVENTE POLAR ORGANICO, O EN UNA PAPILLA EN UN DILUYENTE LIQUIDO ORGANICO POLAR EN EL QUE EL EPIMERO DEL RACEMATO ES PARCIALMENTE SOLUBLE, CON UNA FUENTE DE IONES CIANURO, EN LA AUSENCIA DE UNA BASE, EL ISOMERO, O LA MODIFICACION RACEMICA QUE COMPRENDE EL ISOMERO Y SU ENANTIOMERO, SIENDO MENOS SOLUBLE EN EL SOLVENTE O DILUYENTE QUE EL EPIMERO DEL ISOMERO, O EL RACEMATO QUE COMPRENDE EL EPIMERO DEL ISOMERO Y EL ENANTIOMERO DEL EPIMERO, RESPECTIVAMENTE.
