摘要: Chloro-bis(alkylamino)-s-triazine is prepared by means of the step-wise replacement of two chlorine atoms of cyanuric chloride with alkylamino groups in an alkaline medium comprising water and a liquid organic compound which is a solvent for cyanuric chloride and forms a two-phase system with water, in which a molar excess of alkylamine is used in the second replacement step. Upon completion of the second replacement step the reaction mixture is freed from its aqueous phase and the residual suspension or solution of triazine in the organic compound is admixed with water added in a volumetric quantity of from 30 to 150% with respect to that of said aqueous phase.The chloro-bis(alkylamino)-s-triazine thus produced has high characteristics of handling and formulability.

摘要: The commercial method of preparing chloro-bis(alkylamino)-s-triazine by step-wise replacement of two chlorine atoms of cyanuric chloride by means of alkylamino groups in an alkaline medium comprising water and a liquid organic compound is improved by adding to the reaction product, upon completion of the second replacement step, or during or after the distillation of the organic compound, at least 0.5% by weight with respect to the weight of the chloro-bis(alkylamino)-s-triazine, of minerals chosen from the groups of montmorillonite, paligorskite, vermiculite and chlorite and having a base-exchange capacity of at least 10 milli-equivalents for each 100 grams of said solid, thus deactivating the unreacted alkylamine and the tris(alkylamino)-s-triazines present in the reaction product.
