概要
Nitrogen trioxide appears as a blue liquid with a sharp, unpleasant chemical odor. Density 1.447 g / cm3. Low-boiling (boiling point 3.5 °C) and held as a liquid by compression. Partially dissociates into NO and NO2. Strong irritant to skin, eyes and mucous membranes. Vapors very toxic by inhalation. Used in special purpose fuels. Under prolonged exposure to intense heat the container may rupture violently and rocket.

応用分野
解説N2O3(76.0)．亜硝酸HNO2の無水物である．一酸化窒素と二酸化窒素の等モル混合物を低温(－20 ℃ 以下)にするか，硝酸を三酸化二ヒ素やデンプンで還元すると得られる．2HNO3 ＋ As2O3 → N2O3 ＋ 2HAsO3融点－102 ℃，沸点3.5 ℃．三酸化二窒素，固体と液体は青色，気体は褐色．液体，気体ともに一部一酸化窒素と二酸化窒素に解離している．アルカリ水溶液にN2O3を溶解すると亜硝酸塩が得られる．中性水溶液では亜硝酸になるが，すぐに分解して硝酸と一酸化窒素になる．森北出版「化学辞典（第2版）
用途三酸化二窒素は，亜硝酸塩の製造に用いられるほか，特殊燃料(ロケットなどの推進薬)の酸化剤として用いられる．有毒
