High Quality Content by WIKIPEDIA articles! Potassium picrate, or potassium 2,4,6-trinitrophenolate, is an organic chemical, a picrate of potassium. It is a reddish yellow or green crystalline material. It is a primary explosive. Anhydrous potassium picrate forms orthorhombic crystals. Potassium picrate was first prepared as impure in mid-17th century by Johann Rudolf Glauber by dissolving wood in nitric acid and neutralizing with potassium carbonate. It is commoly made by neutralizing picric acid by potassium carbonate. It was used since 1869. Its chief applications are in pyrotechnics, in some whistle mixes, as a component of explosives (with potassium nitrate and charcoal), propellants (with potassium chlorate), and explosive primers (with lead picrate and potassium chlorate). Potassium picrate is not a very powerful explosive. It is somewhat shock-sensitive. In contact with flame it deflagrates with a loud sound. If ignited in confined space, it will detonate. It is more sensitive than picric acid.
