Abstract
A process for preparing trichloromelamine starting from chlorine and melamine, with intermediate formation of an aqueous suspension of hexachloromelamine, characterized in that hexachloromelamine is solubilized by addition of a water-immiscible solvent, the aqueous phase is separated and the hexachloromelamine solution is brought into contact, in the presence of an activator, with a number of melamine moles which is equal to or lower than the number of moles of the remaining hexachloromelamine.

A process for preparing trichloromelamine starting from chlorine and melamine, with intermediate formation of an aqueous suspension of solid hexachloromelamine, characterized in that the thus formed hexachloromelamine is solubilized by addition of a water-immiscible solvent, the aqueous phase is separated and the resulting substantially anhydrous solution of hexachloromelamine is brought into contact, in the presence of an activator, with a number of moles of non-chlorinated melamine equal to or lower than the number of moles of present hexachloromelamine.
