Two component type of organogel-forming agent working by intermolecular hydrogen bonding

On the basis of the assumption that an equimolar mixture of 2, 4, 6-triamino-1, 3, 5-triazine derivative and barbituric acid derivative forms molecular aggregation through complementary intermolecular hydrogen bonding, two component type of organogel-forming agents were developed. The developed agents consisted of two different components and worked by the formation of intermolecular hydrogen bonding between them. Gelation test using equimolar mixtures was carried out against fourteen solvents, including soybean oil, triolein, benzene, toluene, nitrobenzene, kerosene, light oil, tetrachloromethane, chloroform cyclohexane, N, N-dimethylformamide, 1-propanol, ethyl acetate, and acetone. It was found that equimolar mixtures of appropriate combination of 2, 4, 6-triamino-1, 3, 5-triazine derivative and barbituric acid one having long or branched alkyl chain gelled soybean oil and triolein. FT-IR spectra revealed the formation of defective hydrogen bonds between C=0 and N-H of 2, 4, 6-triamino-1, 3, 5-triazine derivative and barbituric acid one. The X-ray diffraction patterns of cocrystal from acetone and triolein gel suggested the bilayered structure which was built up through intermolecular hydrogen bonding. It was assumed that the fiber-like aggegations were formed by intermolecular hydrogen bonding between 2, 4, 6-triamino-1, 3, 5-triazine derivative and barbituric acid one, then they were juxtaposed and interlocked by van der Waals interaction, finally immobilized soybean oil or triolein.
