What is produced by the high-temperature reaction of melamine?
Thread Content
I used an electric heater to heat the melamine. At first, the triamine sublimated, and it was possible to see clearly that the amount of melamine decreased. However, later on, the remaining melamine formed clumps and turned yellow; continuing to heat it did not result in any further reduction in the amount of remaining melamine. Could it be that at high temperatures, melamine undergoes some internal reaction to form new substances?
Asking myself the question and having just found the answer, melamine, when heated under high temperatures or in conditions with insufficient ammonia partial pressure, loses ammonia to form compounds such as mellamine and melleramine. When heated to 500 degrees, further deamination occurs to produce melon.
The answer is good; could you be more specific?
