摘要: 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.

摘要: In the commercial process for preparing chloro-bis(aklylamino)-s-triazines by step-wise replacement of two chlorine atoms of cyanuric chloride with alkylamino groups in which a molar excess of alkylamine is used in the second replacement step, the formation of tris-(alkylamino)-s-triazines is suppressed by submitting the reaction mixture, after the second replacement step is completed, to a pressure not exceeding 400 mm Hg, at a temperature not exceeding about 55.degree. C. and for a period not exceeding about 15 minutes, thereby removing the excess alkylamine from said reaction mixture by volatilization without substantially removing the other components of the reaction mixture.
