Abstract
Способ получения меламина из мочевины путем осуществления процесса под высоким давлением, при котором твердый меламин получают переносом продукта из реактора, включающего жидкий меламин, COи NH, в газожидкостный сепаратор и последующим переносом расплава меламина, поступающего из сепаратора, в резервуар, где расплав меламина охлаждается с помощью испаряющейся охлаждающей среды, отличающийся тем, что газожидкостное разделение осуществляют добавлением 510- 210моля воды на моль меламина.Международная заявка была опубликована вместе с отчетом о международном поиске.
