|potassium picrate||molecular mass
Potassium picrate was first prepared back in the mid 17th century by J.R. Glauber. The first use for potassium picrate came in 1869, it found its way into explosives, propellents, primers, and pyrotechnics. This explosive is stable and resists shock, friction, etc. It will deflagrate if subjected to flame, and in mixtures with oxidizing agents, it will only burn if ignited, but it has lower sensitivity. This is not a very powerful explosive, it is more suited to pyrotechnics and bullet primers.
Potassium picrate can be prepared by Glaubers original method of dissolving wood in nitric acid then neutralizing the resulting mixture with potassium carbonate. For the modern method, neutralize a hot aqueous solution of potassium carbonate with a hot picric acid solution in a beaker of suitable size, test the solution with litmus paper until neutral. Filter the crystals that separate when the solution cools to collect them and allow to dry.
