Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO INDUSTRIAL DE FABRICACION DE ORTOHIDROXIMANDELATO DE SODIO POR CONDENSACION EN ATMOSFERA INERTE DE FENOL CON ACIDO GLIOXILICO EN SOLUCION ACUOSA, EN PRESENCIA DE UNA AMINA TERCIARIA Y DE CANTIDADES CATALITICAS DE UN CATION METALICO TRIVALENTE A UNA TEMPERATURA INFERIOR A 100 (GRADOS) C REALIZADO DE FORMA CONTINUA EN AL MENOS DOS REACTORES (R1... RN) MONTADOS EN SERIE. EL PRIMERO DE ELLOS ES ALIMENTADO POR UNA CUBA C1 QUE CONTIENE ACIDO GLIOXILICO Y LOS CATIONES METALICOS TRIVALENTES Y POR UNA SEGUNDA CUBA C2 CON EL FENOL Y LA AMINA TERCIARIA. EL MEDIO REACTIVO OBTENIDO A LA SALIDA DEL ULTIMO DE LOS DOS REACTORES Y COMPUESTO POR UNA FASE ACUOSA Y UNA FASE ORGANICA ES TRANSFERIDO AL PRIMERO DE LOS DOS MEZCLADORES DECANTADORES (MD1 Y MD2) MONTADOS EN SERIE. SE RECUPERA LA FASE ACUOSA DEL PRIMER MEZCLADOR DECANTADOR MD1 PARA EXTRAER EL ORTOHIDROXIMANDELATO DE SODIO, MIENTRAS QUE LA FASE ORGANICA RESULTANTE DE MD1 SE TRANSFIERE AL SEGUNDO MEZCLADOR DECANTADOR MD2 Y SE LAVA CON AGUA. LA FASE ORGANICA DEL SEGUNDO MEZCLADOR DECANTADOR MD2 SE TRANSFIERE A LA SEGUNDA CUBA (C2).
