2.4.12 Mercury(II) Fulminate
Mercury(II) fulminate (CAS number 628-86-4) is toxic and highly sensitive to fric-
tion and shock. It is water-insoluble and can be phlegmatized by the addition of fats,
oils, or paran. It is prepared by dissolving mercury in nitric acid with 95% etha-
nol. en, energetic gas and crystals are produced; crystals are ltered by suction
