Ammelide (6-Amino-2,4-Dihydroxy-1,3,5-Triazine) is a triazine and the hydrolysis product of ammeline.

Synthesis

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 170 °C 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.
