ABSTRACT:
A method is provided for separating tris(alkylamino)-s-triazine by-product from chloro-bis(alkylamino)-s-triazines by extracting tris(alkylamino)-s-triazine from an organic solution containing a mixture of tris(alkylamino)-s-triazine and chlorobis(alkylamino)-s-triazine with an aqueous acid solution in the pH-range of 5.4-0.5 and according to a further embodiment of the present invention, treating an alkaline aqueous effluent containing a mixture of chloro-bis(alkylamino)-s-triazine and tris(alkylamino)-s-triazine with an agent capable of reducing the pH value below 5.4 and extracting the chloro-bis(alkylamino)-s-triazine with a water immiscible solvent, the tris(alkylamino)-s-triazine remaining in the aqueous phase.
