Basic information
Thiourea is performed to partial isomerization during melting to form thiocyanurate specific ammonium. It is also used as vulcanization accelerator for rubber and flotation agent for metal minerals, etc. It is formed by the action of hydrogen sulfide with lime slurry to form calcium sulphide, and then with calcium cyanamide (group). Ammonium thiocyanate can also be fused to produce, or the cyanide and hydrogen sulfide produced by the action.
