Ammelide
Encyclopedia
Ammelide is a triazine
and the hydrolysis
product of ammeline
.
at 160-170°C. It can also be synthezised by heating melam
with concentrated
sulfuric acid
for a short time at 190°C.
, 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.
Triazine
A triazine is one of three organic chemicals, isomeric with each other, whose molecular formula is 333 and whose empirical formula is CHN.- Structure :...
and the hydrolysis
Hydrolysis
Hydrolysis is a chemical reaction during which molecules of water are split into hydrogen cations and hydroxide anions in the process of a chemical mechanism. It is the type of reaction that is used to break down certain polymers, especially those made by condensation polymerization...
