# Simple synthesis of thiocyanates

Can sodium thiocyanate be synthesised by combining equimolar amounts of ammonia, sodium hydrosulfide and carbon dioxide in the presence of phosphorous pentoxide by the following reaction: NH3 + NaSH + CO2 -> NaSCN + 2H2O ?

$$\ce{P4O10}$$ would not be much better, forming various forms of condensated phosphoric acid.
