Beschreibung
Zusammenfassung:	An imidazole-isocyanuric acid adduct having the following formula is disclosed: wherein R1 is a member selected from the group consisting of a hydrogen atom, a beta -cyanoethyl group and a beta -[3,5-diamino-s-triazinyl-(1)]-ethyl group, R2 stands for a monovalent hydrocarbon group having up to 17 carbon atoms, R3 is a member selected from the group consisting of a hydrogen atom and an alkyl group having up to 4 carbon atoms, with the proviso that when R1 is a hydrogen atom, R2 is a methyl or phenyl group and R3 is a hydrogen atom and when R1 is a beta -cyanoethyl group, R2 is a phenyl group and R3 is a hydrogen atom, and n is a number of from 0 to 2. This adduct has peculiar characteristics not possessed by ordinary salts. Namely, the adduct is stable in water, and it decomposes in a solvent or under heating. The adduct is valuable as a curing agent for epoxy resins, and it can be utilized for purification of imidazoles.
