摘要: An imidazole-isocyanuric acid adduct having the following formula is disclosed: ##STR1## wherein R.sub.1 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, R.sub.2 stands for a monovalent hydrocarbon group having up to 17 carbon atoms, R.sub.3 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 R.sub.1 is a hydrogen atom, R.sub.2 is a methyl or phenyl group and R.sub.3 is a hydrogen atom and when R.sub.1 is a .beta.-cyanoethyl group, R.sub.2 is a phenyl group and R.sub.3 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.
