A method of preparing silver azide comprising reacting a solution of a silver salt, an azide salt, ammonium hydroxide, and a hydrolysable ester at a temperature in a range of 50° C. to 80° C., wherein the hydrolysable ester reacts with ammonia released by the ammonium hydroxide.
A method of preparing silver azide comprising:
- mixing a silver salt and ammonium hydroxide in water;
- adding an aqueous solution of an azide salt;
- adding a hydrolysable ester, wherein the hydrolysable ester is added in an amount sufficient to neutralize substantially all ammonia released by the ammonium hydroxide;
- and
- heating the mixture.
A method of preparing silver azide comprising:
- adding an aqueous solution of an azide salt (solution B) to an aqueous solution of a silver salt and ammonium hydroxide (Solution A);
- adding a suitable ester that reacts with ammonia released by the ammonium hydroxide;
- and
- heating the solution to a temperature in a range of 50° C. to 80° C.
A method of preparing silver azide comprising:
- adding an aqueous solution of sodium azide (solution B) to an aqueous solution of silver nitrate and ammonium hydroxide (Solution A);
- adding ethylene glycol diacetate;
- and
- heating the solution to a temperature of about 55° C. to about 75° C., wherein the ethylene glycol diacetate reacts with ammonia released by the ammonium hydroxide.
