  • Nitric acid - Wikipedia
    When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%
  • Nitric Acid: Acute Exposure Guideline Levels - Acute Exposure Guideline . . .
    White fuming nitric acid contains 0 5% dissolved nitrogen dixoide while red fuming nitric acid contains 14% dissolved nitrogen dioxide (ACGIH 1991) Inhalation of nitric acid involves exposure to nitric acid as well as nitrogen oxides, such a nitrogen dioxide and nitric oxide
  • Nitric acid - Wikipedia, the free encyclopedia
    Fuming nitric acid is characterized as white fuming nitric acid and red fuming nitric acid, depending on the amount of nitrogen dioxide present At concentrations above 95% at room temperature, it tends to develop a yellow color due to decomposition An alternative IUPAC name is oxoazinic acid
  • LCSS: NITRIC ACID
    Nitric acid also reacts violently with a wide range of inorganic substances including many bases, reducing agents, alkali metals, copper, phosphorus, and ammonia Nitric acid corrodes steel Nitric acid should be handled in the laboratory using the "basic prudent practices" described in Chapter 5 C
  • Multiple Diagnostics of Hybrid Rocket Ignition and Effect of Hypergolic . . .
    The ignition delay and surface-temperature evolution of ammonia-borane-doped paraffin wax exposed to white fuming nitric acid are measured in oxidizer-drop tests The ammonia borane granulometry is varied to investigate the limits of hypergolic ignition and its underlying mechanisms
  • NITRIC ACID - Springer
    The SABAR (Strong Acid By Azeotropic Rectification) process makes nitric acid by the atmospheric oxidation of ammonia The nitrous gases from the oxidation are absorbed in azeotropic nitric acid in the presence of oxygen under pressure
  • CHAPTER ONE INTRODUCTION - University of Diyala
    o as fuming nitric acid Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as white fuming nitric acid or red fuming nitric acid, at oncentrations above 95% Nitric acid is also commonly used as strong oxidizing agent The earliest known written description of t nitric acid is
  • High-speed multi-spectral imaging of the hypergolic ignition of ammonia . . .
    Ammonia borane (AB) is also highly hypergolic with white fuming nitric acid (WFNA) while lacking the health hazards associated with more conventional hypergolic fuels (e g hydrazine and its derivatives)
  • Nitric acid | EBSCO Research Starters
    Fuming nitric acid can be further divided into white or red fuming nitric acid, depending on the amount of nitrogen dioxide the solution contains The fumes from nitric acid have a characteristic choking odor The smell is alternately described as cloyingly sweet or very acrid and harsh
  • NITRIC ACID, WHITE FUMING | Canyon Components
    White fuming nitric acid (WFNA) is a highly concentrated and reactive form of nitric acid used primarily as an oxidizer in rocket propellants It contains dissolved nitrogen oxides, making it extremely corrosive and reactive WFNA is also employed in some industrial processes requiring strong oxidizing conditions
