Abstract

PROCEDIMIENTO PARA LA OBTENCION DE DERIVADOS DE ISOPROPILFENILACETATO DE CIANOBENCILO, DE FORMULA (I), EN LA QUE N VALE 0-2; R Y X PUEDEN SER VARIOS RADICALES; R ES HIDROGENO O METILO, Y X ES HALOGENO O METILO. CONSISTE EN LA PRECIPITACION DE CRISTALES ENRIQUECIDOS EN EL PAR ENANTIOMERO CONSTITUIDO POR R LFA-ISOPROPOLFENILACETATO DE S-ALFA-CIANOBENCILO Y S-ALFA-ISOPROPILFENIALCETATO DE R-ALFACIANOBENCILO, EN UNA DISOLUCION DEL R,S-ALFA-ISOPROPOLFENILACETATO DE R-S-ALFA-CIANOBENCILO RACEMICO; SEPARACION DE LOS CRISTALES; REDISOLUCION DE LOS MISMOS Y TRATAMIENTO DE LA DISOLUCION CON UNA BASE PARA EPIMERIZAR EL PAR ENANTIOMERO A LA MEZCLA RACEMICA; RECIRCULAR LA MEZCLA RACEMICA Y RECUPERAR LAS AGUAS MADRES ENRIQUECIDAS EN EL PAR ENANTIOMERO. ESTOS COMPUESTOS TIENEN APLICACIONES EN AGRICULTURA COMO PESTICIDAS.
