Abstract
Oppfinnelsen vedrører en fremgangsmåte for å rense melamin, der urent melamin varmes opp til et temperaturområde over 325°C, men lavere enn smeltepunktet for melamin, som avhenger av det gjeldende ammoniakktrykket. I tillegg holdes det urene malaminet innenfor nevnte temperaturområde under et ammoniakktrykk som strekker seg fra l til 150 bar i en tidsperiode som varer fra l minutt opptil 20 timer. Melaminet frembringes i fast form. Etterpå frigis melaminet fra trykk og avkjøles i en hvilken som helst rekkefølge.
