ニトロシルフルオリド 化学特性,用途語,生産方法

• 化学的特性

  Colorless gas.Attacks glass severely and corrodes quartz.

• 物理的性質

  Colorless gas when pure; often appears bluish because of impurities; density 2.176 g/L; liquefies at -56°C; density of liquid 1.326g/mL at its boiling point; solidifies at -134°C; density of solid 1.719 g/cm³; reacts with water.

• 使用

  Oxidizer in rocket propellants; stabilizing agent for liquid SO3; fluorinating agent.

• 製造方法

  Nitrosyl fluoride may be prepared by the reaction of fluorine with nitric oxide:
  F₂ + 2NO → 2FNO
  Nitrosyl fluoride also can be obtained by heating nitrosyl fluborate, NOBF₄, and sodium fluoride:
  NOBF₄ + NaF → NaBF₄ + FNO
  Nitrosyl fluoborate required for the above preparation may be obtained by dissolving boric acid in 40% HF, concentrating the solution till it fumes, and purifying the NOBF₄ formed by sublimation in a vacuum.
  Nitrosyl fluoride also can be produced by the action of nitrosyl chloride with silver fluoride:
  NOCl + AgF → FNO + AgCl
  All preparations must be done in complete absence of water.

• 危険性

  Toxic by inhalation, irritant to skin and mucous membranes.

• 安全性プロファイル

  A poison. A severe irritant to skin, eyes, and mucous membranes. Reacts vigorously with glass; corrodes quartz. Explosive reaction with alkenes, oxygen difluoride. Incandescent reaction with metals (e.g., antimony, bismuth,tin, sodium); nonmetals (e.g., a
