Acidic process to manufacture NTA


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 chemical equation for (hexamethylenetetramine react with hydrogen cyanide in sulfuric acid to yield triscyanomethylamine).

( CH2)6N4 + 6 HCN + H2SO4 => 2 N(CH2CN)3 + (NH4)2SO4

N( CH2CN)3 + 3 NaOH + 3 H2O => N(CH2COONa)3 + 3 NH3
