Abstract

Способ получения меламина путем превращения мочевины в присутствии твердого катализатора в одном или нескольких последовательно подключенных реакторах в диапазоне температур от до , охлаждения и фильтрации газа, образуемого в процессе преобразования мочевины, отделения меламина путем десублимации и возврат части газа, оставшейся после отделения меламина («циркуляционного газа»), в реактор или реакторы, причем все вышеупомянутые стадии осуществляют под давлением в диапазоне от 4 бар абс. до 10 бар абс.
