Some reactions occurring between KSCN and molten NANO<sub>3</sub>-KNO<sub>3</sub>
When KSCN is added to molten NaNO<sub>3</sub> -KNO<sub>3</sub> eutectic within the range of 230-316°C, a complex and a relatively violent chemical reaction takes place until a KSCN concentration of ca. 1 mequiv KSCN/100 g eutectic has been added; further addition produces onl...

| Sumario: | When KSCN is added to molten NaNO<sub>3</sub> -KNO<sub>3</sub> eutectic within the range of 230-316°C, a complex and a relatively violent chemical reaction takes place until a KSCN concentration of ca. 1 mequiv KSCN/100 g eutectic has been added; further addition produces only a small residual chemical reaction. The reaction yields NO<sub>2</sub>, SO<sup>2</sup><sub>4</sub> ions and basic ionic species in the melt and NO<sub>2</sub>, CO<sub>2</sub>, (CN)<sub>2</sub>, N<sub>2</sub>O and minor quantities of other gaseous products. The reaction is interpreted in terms of ionic equilibria involving NO<sub></sub>, NO<sub>2</sub>, SCN, O<sup>2</sup><sub>2</sub>, O<sp>2</sup>, O<sub>2</sub> and O<sup>2-</sup> ions and O<sub>2</sub> as principal reacting species. |
