Abstract

PROCEDIMIENTO PARA LA OBTENCION DE METILOLMELAMINAS MONOMERAS. CONSISTE EN AÑADIR FORMALDEHIDO A MELAMINA CON ETERIZACION SIMULTANEA CON ALCOHOLES A TEMPERATURAS ELEVADAS; LA REACCION TIENE LUGAR EN UNA SOLA ETAPA SEGUIDO DE EVAPORACION DEL ALCOHOL Y DE LA FORMAMIDA EN EXCESO. LA REACCION TIENE LUGAR EN MEDIO ANHIDRO, EMPLEANDOSE EL PARAFORMALDEHIDO EN UNA PROPORCION MOLAR ENTRE MELAMINA:FORMALDEHIDO:ALCOHOL DE 1:5-10:6-20 CON UN PH DE 7 A 8 Y TEMPERATURAS COMPRENDIDAS ENTRE 50 Y 90 C Y TIEMPOS DE REACCION DE 3 A 30 HORAS EN ATMOSFERA DE NITROGENO.
