Abstract

LOS 4H-1,2,4-TRIAZOLES SE ISOMERIZAN A LOS CORRESPONDIENTES 1H-1,2,4 TRIAZOLES EN PRESENCIA DE UN AGENTE ISOMERIZANTE CONSISTENTE EN UN HALURO ORGANICO O EPOXIDO. ESTE PROCESO REPRESENTA UN UTIL METODO PARA LA RECUPERACION DE 1H-1,2,4 TRIAZOLES FUNGICIDAS, ANTIMICOTICOS O MICROBICIDAS MEDIANTE LA ISOMERIZACION DEL NO DESEADO 4H-1,2,4-TRIAZOL, PRODUCTO SECUNDARIO QUE SE FORMA DURANTE LA PREPARACION.
