the 1 h nmr spectrum solvent dmso and the internal standard tms of atu2cg is shown in fig4 the curve showing the proton integral ratio of each peak is additionally shown in fig4 in the diagram the symbols 1 through 8 denote the symbols of the hydrogen atoms linked to the carbon atoms of the atu2cg the reaction of sodium dicyanamide with 2 4 6 triamino s triazine hydrochloride proceeds as shown by the following formula 6 to produce 2 cyanoguanidyl 4 6 diamino s triazine as aimed at str13 this synthesis was carried out in accordance with the following procedure in an eggplant type flask having an inner volume of 100 ml and equipped with a dimroth condenser 8 9 g 0 10 mol of sodium dicyanamide 1 63 g 0 10 mol of 2 4 6 triamino s triazine hydrochloride and 20 ml of n butanol were charged then the flask containing the reactants was placed in an oil bath and the reactants were stirred with a magnetic stirrer under a refluxed condition and thus left reacting for 5 hours at about 118 u00b0 c after the reaction was completed the reaction solution was distilled under a reduced pressure in an evaporator to expel the reaction solvent the residue of the distillation and a mixture of water acetone mixing ratio of 1 0 1 0 added thereto were mixed thoroughly the resultant mixture was passed through a glass filter the solid consequently separated was dried in a vacuum drier at 80 u00b0 c for 8 hours to obtain 0 55 g of white 2 cyanoguanidyl 4 6 diamino.
