    Abstract: Compounds are prepared of the formula (I) where R' is a t-alkyl group having 4 to 18 carbon atoms, preferably t-butyl, t-amyl or t-octyl and R is a straight or branched chain alkyl group with 1 to 18 carbon atoms, preferably 1 to 10 carbon atoms or an alkyl group substituted with one or more phenyl group or a halogen atom, particularly a chlorine atom, or a cycloalkyl group with 3 to 8 carbon atoms, particularly cyclopropyl, which can be substituted by one or more 1 to 3 carbon atom alkyl groups or one or more halogen atoms, preferably chlorine, or phenyl or naphthyl or a five membered heterocyclic group or such phenyl, naphthyl or heterocyclic group substituted by halogen atoms, nitro groups, alkyl or alkoxy with 1 to 5 carbon atoms by condensing in acid medium an acyl cyanide of the formula R-CO-CN (II) where R is as defined above with either (a) a tertiary alcohol of the formula HO-R'(III) in which R' is as defined above, or preferably (b) an alkene of the formula (IV) where R1 and R2 are the same or different and are hydrogen or an alkyl group and wherein R3 and R4 are the same or different and wherein the alkyl groups in each case can be 1 to 15 carbon atoms. Some of the compounds are new. They are useful as intermediates for synthesizing herbicides and can be used directly as fungicides.

    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.
