Abstract

PROCEDIMIENTO PARA LA PREPARACION DE MELAMINA RECRISTALIZADA PARA USO COMO FERTILIZANTE DE LAS PLANTAS SIN EFECTOS FITOTOXICOS PROVOCADOS POR ELLA. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, LA MELAMINA COMERCIALMENTE PRODUCIDA, QUE CONTIENE IMPUREZAS FITOTOXICAS, SE LAVA CON AGUA, SE FILTRA Y LAS AGUAS MADRES, QUE CONTIENEN LOS COMPONENTES SOLUBLES Y ENTRE ELLOS LAS IMPUREZAS FITOTOXICAS, SE EVAPORAN A SEQUEDAD; SEGUNDA, EL RESIDUO DE MELAMINA OBTENIDO DE LA EVAPORACION SE RECRISTALIZA A TEMPERATURA AMBIENTE; TERCERA, EL PRODUCTO RECRISTALIZADO SE LAVA CON AGUA, SE FILTRA Y SE RECOGEN LAS AGUAS MADRES, QUE SE MEZCLAN CON AGUAS MADRES PROCEDENTES DE LA PRIMERA ETAPA; CUARTA, LA MEZCLA DE AGUAS MADRES SE EVAPORA A SEQUEDAD Y EL RESIDUO OBTENIDO SE RECRISTALIZA A TEMPERATURA AMBIENTE, REPITIENDOSE EL CICLO; Y POR ULTIMO, LA MELAMINA CRISTALINA SOLIDA RECOGIDA EN LAS OPERACIONES DE FILTRADO, DE LA QUE SE HAN SEPARADO LAS IMPUREZAS FOTOTOXICAS, SE SECA POR MEDIOS ADECUADOS Y SE EMPAQUETA PARA SUUTILIZACION. DE USO EN LA FERTILIZACION DE PLANTAS COMO UNA FUENTE DE NITROGENO, ESPECIALMENTE PARA ARBOLES Y ARBUSTOS, BIEN SEA SOLA O MEZCLADA CON UN HERBICIDA DE LIBERACION CONTROLADA. O
