A benzene solution (50 ml) of 5,3-dibutyl allophanoyl chloride (0.1 mole) was prepared by reaction of phosgene with 1,3-dibutyl urea by the method of Example 2. This material was reacted with 16.0 g (0.2 mole) of potassium cyanate as described above. After work-up, 9.3 g (38% yield) of dibutyl isocyanuric acid was obtained; m.p. 86°-88° C. IR and nmr analysis was consistent with the assigned structure.
