Infobox references

Tetryl (IUPAC: 2,4,6-trinitrophenylmethylnitramine) is an explosive compound used to make detonators and explosive booster charges. It has the chemical formula C7H5N5O8.

Properties

Chemical

Tetryl burns when ignited, giving off black smoke.

Physical

Tetryl is a yellow solid, insoluble in water.

Explosive

Tetryl explodes when subjected to strong heating. Its detonation velocity is 7,570 m/s. It has a R.E. factor of 1.25.

Availability

Tetryl is sold as detonators. Purchase requires an explosive permit.

Preparation

Tetryl can be made by adding dimethylaniline to a mixture of conc. nitric acid and sulfuric acid under controlled conditions.

Projects

  • Make detonators
  • Make tetrytol

Handling

Safety

Tetryl is toxic and explosive. Should be handled with care and proper protection.

Storage

Should be stored for short periods of time, in spark-free containers.

Disposal

Can be destroyed via controlled incineration.

Another method involves the slow and controlled addition in Fenton's reagent.
