    Abstract: 1299152 Amino-s-triazines DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 3 June 1971 [4 June 1970] 18786/71 Heading C2C Amino-s-triazines of general formula in which X represents a methyl mercapto group or -NR 5 R 6 , and R 1 -R 6 (which may be the same or different) each represent H or a C 1-6 linear or branched alkyl group which can also be substituted one or more times by -OR groups in which R represents a linear or branched C 1-4 alkyl radical, are made by converting at least one methylmercapto group in an s-triazine compound of formula in which Y and Z each represent a methyl mercapto group, or Y represents the group -NR 1 R 2 and Z represents -NR 3 R 4 , to an amino or substituted amino group as defined above in connection with Formula (I), by reaction at elevated temperature with ammonia or the amine from which the corresponding substituted amino group is derived.

    Abstract: 1,176,770. Substituted triazines. DEUTSCHE GOLD-UND SILBER SCHEIDEANSTALT. 5 July, 1968 [7 July, 1967; 30 Dec., 1967], No. 32132/68. Heading C2C. Substituted 2 - mercapto - 4,6 - dichloro - 8 - triazines of the formula where R is cycloalkyl, alkenyl, aralkyl or alkyl with 1-18 carbon atoms which may optionally be substituted by one or more -OR 1 , SR 1 or -CN groups, where R 1 is C 1-4 alkyl, are prepared by reacting cyanuric chloride with a mercaptan of formula H-S-R, on a mercaptide thereof, in a heterogeneous system comprising water and at least one waterimmiscible organic solvent inert to the cyanuric chloride, optionally in the presence of an inorganic hydrogen chloride acceptor (which must be present if the free mercaptan is used), with thorough mixing of the phases and at a temperature below the boiling point of the organic solvent, reduced or elevated pressures may be used if desired. Specified mercaptides are those of silver, mercury, zinc, lead and alkali metals and many suitable solvents are specified. It is desirable to use a pH value below 8, and the reaction may be carried out continuously.
