    摘要： A process relating to the separation of melamine from hot synthesis gas mixtures is described, wherein such gases are contacted directly with a urea melt containing ammonium carbamate, so that the desublimation heat released as the melamine is converted from the vapor to the solid state is utilized for the decomposition of the ammonium carbamate to release ammonia and carbon dioxide.

    摘要： The subject of the invention is a process for the manufacture of water-soluble condensation products of hydroxymethylphosphonium compounds and a 1,3,5-triazine characterised in that (a) 1 mol of a tetrakis-(hydroxymethyl)-phosphonium compound is condensed with (b) 0.02 to 0.1 mol, preferably 0.05 to 0.1 mol of optionally methylolated 1,3,5-triazine which is substituted by at least one primary amino group, at 40* to 120*C, optionally in the presence of formaldehyde or a formaldehyde-releasing agent and optionally in the presence of an inert organic solvent, the condensation is optionally thereafter continued at temperatures of 100* to 150*C and, if appropriate, free hydroxyl groups are etherified at least partially with at least one alkanol with 1 to 4 carbon atoms and, if appropriate, the salts of the condensation products are converted into the corresponding hydroxides. The condensation products are used for flameproofing organic fibre material, especially textiles.
