Ammonium thiocyanate use

Ammonium thiocyanate NH4NCS is a achromatic hygroscopic apparent compound. It is acrid in baptize (54% wt at 0°C and 61% wt at 20°C). It dissolves exothermically. Ammonium thiocyanate aswell acrid in aqueous ammonia, ethanol, alcohol and acetone. It forms hydrates and ammines. It was begin that ammonium rhodanide atom has thiocyanate geometry - NH4S=C=N. Being acrimonious aloft 140°C ammonium rhodanide boring converts into thiourea H2NC(S)NH2. Ammonium thiocyanate is of low toxicity, afterwards assimilation it can could cause xanthopsia - eyes of altar in chicken light.

Uses:

Ammonium thiocyanate is used:

as a feedstock in bartering thiourea preparation;

as bathrobe abettor in bolt dyeing;

for animate etching;

as a balance or accelerator in photography;

as a band-aid basic in electroplating;

as a reagent in analytic allure in rhodanometric and mercurimetric haloids and cyanides analyses. Aswell it acclimated in photocolorimetry for iron, cobalt, molibdenum and added ions determination;

as a antecedent in authoritative added asleep thiocyanates such as copper, sodium, calcium, potassium and added derivatives;

as an average in fungicides, pesticides and pharmaceuticals production;

as a basic of freezing solutions;
