Infobox disclaimer and references

Ammelide (6-Amino-2,4-Dihydroxy-l,3,5-Triazine) is a triazine and the hydrolysis product of ammeline.


Ammelide can be obtained by heating dicyandiamide with aqueous ammonia at 160-170°C. It can also be synthezised by heating melam with concentrated sulfuric acid for a short time at 190°C.

Chemical property

Ammelide forms salts with both acids (hydrochloric acid, nitric acid, sulfuric acid)and bases (sodium hydroxide, ammonium, calcium hydroxide).

Ammelide decomposes at 170oC with water to form carbon dioxide and ammonia. It can be converted into cyanuric acid by oxidizing agents (e.g. potassium permanganate) or by boiling with acids or alkalies.
