Melamine → HCID 9815571, compound

Participants

Reaction Steps

In a stainless steel autoclave of an inner volume of 100 ml, 1.26 g (10 mmol) of melamine, 250 mg of 5% Pd—C catalyst, and 30 ml of 1,4-butanediol were charged. After the inside of the reaction system was sufficiently substituted with nitrogen gas, 10 kg/cm2 of hydrogen gas was introduced under pressure at normal temperature. Then, the temperature was elevated while stirring, and after the temperature reached 260° C., the reaction was carried out at the same temperature for further 2 hours. After cooling, the reaction mixture was taken out and quantitative analysis of the reaction product was performed under the above analytical conditions. As a result, the reaction conversion rate of the starting material melamine was 48.1% and it was confirmed that there were produced only 22.0% of 2,4-diamino-6-(4-hydroxybutylamino)-1,3,5-triazine and 6.7% of 2-amino-4,6-bis (4-hydroxybutylamino)-1,3,5-triazine as the products, and an obvious decrease in activity as compared with the mixed catalyst systems was confirmed.
