PEL =Ammelide (6-Amino-2,4-Dihydroxy-l,3,5-Triazine) is a
triazine and thehydrolysis product ofammeline .ynthesis
Ammelide can be obtained by heating
dicyandiamid e with aqueousammonia at 160-170°C. It can also be synthezised by heating melam with concentratedsulfuric 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 andammonia . It can be converted intocyanuric acid by oxidizing agents (e.g.potassium permanganate ) or by boiling with acids or alkalies.References
