Picric Acid Explosion - Chemistry LibreTexts
网页2023年2月22日 · Picric acid is in the same family of nitroaromatic explosives as trinitrotoluene (TNT). It is no longer used as an explosive because of this type of reaction. A shock-insensitive explosive compound that forms shock-sensitive explosive salts with metals (such as lead) is too unwieldy for most usual applications.
