    Abstract: There is provided a process, preferably continuous and in a given case successive, substitution of one or two chlorine atoms of cyanuric chloride by one or two amines, which may be the same or different, in the presence of an acid acceptor and in the presence of an organic solvent, particularly for the production of 2-alkylamino-4,6-dichloro and preferably for the production of 2,4-di(alkylamino)-6-chloro-s-triazines wherein there is added 1.00 to 1.05 mole, preferably 1.00 to 1.03 mole of a first amine to a 4.5 to 50 weight % suspension or solution of cyanuric chloride in a mixture of 65 to 85 weight % of xylene, toluene, ethylbenzene, benzene and/or an aliphatic or cycloaliphatic hydrocarbon with 5 to 10 carbon atoms (toluene being preferred) and 35 to 15 weight % of a ketone with 3 to 8 carbon atoms, preferably acetone, while maintaining the temperature between about 0 and about 20 DEG C, preferably about 10 to 18 DEG C., continuously so regulating the pH value of the reaction mixture obtained in accordance with the reaction time by addition of alkali and in a given case, water so that this corresponds to a point within the area bounded by lines ABCD of FIG. 1, which runs through the area beginning with the reaction time t,(step 1)= 0 until reaching a position in the area bounded by the lines BCEF and after reaching a pH of 7.0, preferably 7.2 maintains a temperature of about 10 DEG to about 60 DEG C., preferably about 25 DEG to 40 DEG C., after addition of 0.96 to 1.05, preferably 0.98 to 1.02 equivalents of alkali per mole of cyanuric chloride, adding at least an equimolar amount, preferably 1.00 to 1.02 mole of the second amine per mole of cyanuric chloride and continuously so adjusting the pH value of the reaction mixture obtained depending on the reaction time by addition of alkali that this corresponds to a point within the area which is defined by lines GHIJ in FIG. 3 which passes through the band beginning with the reaction time t(step 2)= 0 of the second reaction step until reaching a position in the area bounded by the lines HIKL and thereby maintaining a temperature of 40 to 70 DEG C., preferably 45 DEG to 55 DEG C. and thereafter working up the product in known manner wherein t1 is a time of 4 to 10 hours, preferably about 7 hours and t2 is a time of 2 to 8 hours, preferably about 6 hours and wherein the B C corresponds to the equation, pH = -(12.6/t1)+ 14.35 and the line H I corresponds to the equation pH = -(24,857/t2)+ 23.9285. There are also disclosed novel, purified mono and bis alkylamino-cyanoalkylalkylamino - s - triazines.

    Abstract: There is provided a process for the production of a solution or suspension of cyanuric chloride in a water containing organic solvent wherein the liquid cyanuric chloride and the organic-aqueous solvent are mixed together while being agitated, the liquid cyanuric chloride at a temperature between its melting point and 200 DEG C. is led into the flowing organic-aqueous solvent with a velocity of Vcy (in kg per hour) wherein where P is the desired concentration of cyanuric chloride in the solution or suspension to be produced in weight %, PLM is the concentration of cyanuric chloride in the solvent used which also includes O, VLM is the velocity of the solvent added in kg/h, AND PLM, VLM and TLM, the temperature of the added solvent, are so selected that the expression does not exceed the boiling temperature in DEG C. of the solvent used and wherein Cp(LM) and Cp(Cy) signify the specific heat capacities in cal. x g 1 x ( DEG degree C) 1 of the solvent and cyanuric chloride respectively, whereupon in a given case within at most 3 minutes after bringing the cyanuric chloride and solvent into contact the flowing mixture is cooled to the desired storage temperature.
