Preparation of cyanogen azide
Sodium azide was suspended in dry acetonitrile, and cyanogen chloride was distilled into the mixture at a rate to maintain the temperature below 12° C. The solution was allowed to warm to room temperature and filtered to remove sodium chloride. The use of dry solvents is important to avoid the formation of explosive, solid by-products, and care also must be taken to avoid separating cyanogen azide from solution through evaporating low-boiling solvents, cooling saturated solutions, or freezing the solvent.
