Lead picrate, or more properly, basic lead picrate, is an energetic, toxic, and explosive lead salt.
Contents
Properties
Physical
Lead picrate is an orange, very dense non-hygroscopic lead compound. Its melting and boiling point are both unknown, as it tends to deflagrate or detonate before it reaches such a temperature.
Chemical
Explosive
Lead picrate is moderate sensitive to shock and heat, but has high friction sensitivity.
Availability
Lead picrate is not sold by any supplier, due to its instability.
Old reagent bottles containing picric acid that have lead in their lid will accumulate small amounts of lead picrate, which may be set off if one tries to open the bottle.
Preparation
Lead picrate can be made by adding lead oxide to picric acid, in a solution.[1]
Manufacturing, storing and handling this compound may require an explosive permit, depending on the country.
Projects
- Amateur detonators
Handling
Safety
Lead picrate is extremely toxic. It is also a sensitive explosive, which is higher if the material is dry.
Storage
Due to its sensitivity, lead picrate should not be stored in large amounts. Wet powder is less sensitive than dry material.
Disposal
Small amounts of this material can be neutralized via controlled detonation. However, the disposal of larger amounts is complicated. One way is to add the material in water, where it's slowly and gently oxidized using various oxidizing solutions, like Fenton's reagent, ozone, or some other oxidizer. The final product will contain insoluble lead oxide precipitate, which is toxic, and needs to be either recovered or taken to a hazardous waste disposal center.
