hydrazoic acid การใช้

• Some azides are produced by treating the carbonate salts with hydrazoic acid.
• When combined with slightly acidic solutions, it generates deadly and explosive hydrazoic acid.
• When combined with water, it forms deadly hydrazoic acid.
• Calculated major resonance structures of diazomethane and hydrazoic acid ( doi = 10.1021 / ja00475a007)
• Aliphatic alcohols give azides via a variant of the Mitsunobu reaction, with the use of hydrazoic acid.
• Hydrazoic acid is soluble in water.
• Resonance structures can be drawn to hydrazoic acid bears the largest negative character at the " internal " nitrogen atom.
• I have the acidity constant for a hydrazoic acid ( HN3 ) . is that used to write the balanced equation?
• Betterton said just 6.5 parts of sodium azide per 1 million parts of slightly acidic water will create hydrazoic acid, a deadly explosive.
• Additionally, furfural has been converted to 2-furonitrile by a number of reagents, including hydrazoic acid-perchloric acid, hypervalent iodine ( III ) and n-bromosuccinimide.
• Betterton said just 6 . 5 parts of sodium azide per 1 million parts of slightly acidic water will create hydrazoic acid, a deadly explosive.
• Undiluted hydrazoic acid is dangerously explosive with a standard enthalpy of formation ? f H o ( l, 298K ) = + 264 kJmol  " 1 ).
• The all gas-phase iodine laser ( AGIL ) mixes gaseous hydrazoic acid with chlorine to produce excited nitrogen chloride, which is then used to cause iodine to lase; this avoids the liquid chemistry requirements of COIL lasers.
• AGIL uses a reaction of chlorine atoms with gaseous hydrazoic acid, resulting in excited molecules of chloronitrene ( ), which then pass their energy to the iodine atoms much like the singlet oxygen does in COIL . The iodine atoms then emit the laser radiation itself.
• The bis ( triphenylphosphino ) iminiumhexaazidosilicate salt ( ( PPN ) 2 Si ( N 3 ) 6 ) on the other hand is relatively stable . the compound melts at 214 癈 and shows in the DSC measurement at 250 癈 a reaction One mass spectrometry coupled thermogravimetric analysis investigation indicated as reaction products nitrogen, silicon tetraazide and hydrazoic acid.
• When the condition of the munitions was originally assessed there was concern that copper azide, an extremely sensitive explosive, would be produced through reaction between lead azide and copper from fuse components ( lead azide would react with water vapour, rather than liquid water, to form hydrazoic acid, which could react with copper in the detonating cap to form copper azide ).
