Synthesis of Ammonium Thiocyanate by Phase Transfer Catalysis
Abstract:
Ammonium thiocyanate was prepared in 2 steps from aqueous ammonia and carbon disulfied by phase transfer catalysis in yield of 72.7%, when catalysts consisted of OP-4 and OP-21 in mole ratio of 4:6. The effects of reaction temperature, time, mole ratio of OP-4 to OP-21 and conparison with other catalysts on the reaction were descurved.
