Abstract

Способ очистки меламина, при котором неочищенный меламин берут в температурном интервале, который лежит выше 325°C и ниже температуры плавления меламина, зависящей от использованного давления аммиака, и выдерживают под давлением аммиака от 1 до 150 бар в течение от 1 мин до 20 ч в указанном температурном интервале, причем меламин представляет собой твердое вещество. Затем в любом порядке сбрасывают давление и охлаждают.Международная заявка была опубликована вместе с отчетом о международном поиске.
