ABSTRACT:
Chloro-bis(alkylamino)-s-triazines are prepared by step-wise replacement of two chlorine atoms of cyanuric chloride by reaction with amines and alkali metal hydroxide in a medium comprising water and a liquid organic compound which is a solvent for cyanuric chloride and is substantially immiscible with water, the first step being carried out by contacting a first amine with a reaction medium containing the cyanuric chloride and the whole of the alkali metal hydroxide used for the step-wise replacement.
