Potassium thiocyanate - colorless crystals of the monoclinic system, deliquescent in moist air. At 430 ° C the drug becomes blue color when cooled again decolorized. At 500 ° C decomposed. Potassium thiocyanate is readily soluble in water, very soluble in ethyl alcohol. During the crystallization of potassium thiocyanate solutions at low temperature is obtained crystalline KNCS · 0,5H2O.
Potassium thiocyanate can be prepared by the reaction of ammonium thiocyanate with potassium hydroxide:
NH4NCS + KOH = KNCS + + H2O NH3b
Potassium thiocyanate (potassium thiocyanate, sulfocyanate thiocyanate) KCNS used
• in the textile industry;
• in photography;
• in organic synthesis (for example, thiourea for artificial dyes or mustard oils), for thiocyanates, cooling mixtures, insecticides, etc.
