Simultaneous oxidation of cyanide and thiocyanate at high pressure and temperature

- The oxidation rate of SCN− was greatly enhanced by the presence of CN−.
- The degradation of mixtures was significantly affected by temperature and pressure.
- A free-radical pathway was proposed, CN− and CNO− being the reaction intermediates.
- The principal reaction products were found to be HCOO−, NH3 and SO42−.
- One of the parallel routes gives the found products and the other N2, CO2 and H2.
