I found this technique from the patent but couldn't form the chemical equation.

Ammonia water, sodium hydroxide and hydroxyacetonitrile are utilized as raw materials to synthesize the nitrilotriacetic acid.

Anyone can help me to form chemical equation for this reaction?

In the acid process, ammonia is reacted with formaldehyde to form hexamethylenetetramine, which is subsequently treated with hydrogen cyanide in sulfuric acid to yield triscyanomethylamine. The cyano-intermediate is then saponified with sodium hydroxide to form Na3NTA. Can anyone help me with chemic...
