SODIUM THIOCYANATE LR
In the metallurgical industry, sodium Thiocyanate has a wide range of uses. It can be used in
Sodium thiocyanate is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion.
In the metallurgical industry, sodium Thiocyanate has a wide range of uses. It can be used in electroplating, cyanide copper plating, and nickel plating. The compound can also be used in cyanide brass plating. Sodium Thiocyanate is effective in metal coating and plating because it eliminates oxides, acting as a corrosion inhibitor. Metal plating with sodium Thiocyanate gives them a shiny finish.
Sodium thiocyanate is employed to convert alkyl halides into the corresponding alkylthiocyanates. Closely related reagents include ammonium thiocyanate and potassium thiocyanate, which has twice the solubility in water. Silver thiocyanate may be used as well; the precipitation of insoluble silver halides help simplify workup. Treatment of isopropyl bromide with sodium thiocyanate in a hot ethanolic solution affords isopropyl thiocyanate.[4] Protonation of sodium thiocyanate affords isothiocyanic acid, S=C=NH (pKa = −1.28).[5] This species is generated in situ from sodium thiocyanate; it adds to organic amines to afford derivatives of thiourea.
