응용 분야
용도Potassium Thiocyanate has been used as a catalyst in a one-pot reaction of dialkyl acetylenedicarboxylates with indane-1,3-dione. Potassium Thiocyanate has been used as a selective bacterial inhibitor to create ESS-3 broth to allow co-enrichment of the target pathogens and suppress growth of some non-target pathogens
일반 설명Potassium thiocyanate is an inorganic potassium salt. Phase transitions in potassium thiocyanate (KSCN) have been investigated by X-ray diffraction studies. The order-disorder type transition with respect to the orientation of the thiocyanate ions was identified. Its polarized infrared spectrum has been reported. It participates in the ring-opening of aziridines. The reaction was carried out in the presence of sulfated zirconia to afford the corresponding β-aminothiocyanates.
제조 방법
Potassium thiocyanate may be made by adding caustic potash to a solution of ammonium thiocyanate, followed by evaporation of the solution. NH4SCN + KOH →KSCN + NH4OHAlso, the compound can be prepared by heating potassium cyanide with sulfur:KCN + S →KSCN.
