METHOD FOR MELAMINE TREATMENT OBTAINED BY SYNTHESIS IN HIGH- PRESSURE REACTOR Russian patent published in 2005 - IPC

FIELD: organic chemistry.

SUBSTANCE: claimed method includes conditioning and cooling of NH₃-containing melamine melt from melamine high-pressure reactor after separation of exhaust gases. Then melt is fed into apparatus with fluidized bed wherein substantially NH₃ is used as fluidizing gas, decompressed, cooled and solidified with solid melamine or solid inert materials, wherein cold NH₃, preferably liquid NH₃ is added to circulating gas which is reunified by cyclone and/or filters. As a result solid melamine is deposited.

EFFECT: method of high yield; target product of high purity.
