Abstract

PROCEDIMIENTO DE PREPARACION DE ALDOXIMAS AROMATICAS, TALES COMO BENZALDOXIMA, HACIENDO REACCIONAR EL ALFA, ALFA-DIHALURO CORRESPONDIENTE, TAL COMO CLOROBENZAL, CON UNA SAL DE HIDROXILAMINA EN PRESENCIA DE UN EXCESO DE UNA BASE ACUOSA SUFICIENTE PARA MANTENER EL PRODUCTO OXIMICO EN SOLUCION. LAS IMPUREZAS ORGANICAS PUEDEN SEPARARSE POR FASES DE LA MEZCLA DE REACCION. A CONTINUACION, SE NEUTRALIZA LA SOLUCION ACUOSA QUE CONTIENE EL PRODUCTO OXIMICO PARA SEPARAR UNA FASE OXIMICA, QUE PUEDE RECUPERARSE POR DECANTACION O EXTRACCION EN DISOLVENTE.
