Dinitrogen trioxide (also known as nitrous anhydride) is the inorganic compound with the formula N 2 O 3. It is a nitrogen oxide. It forms upon mixing equal parts of nitric oxide and nitrogen dioxide and cooling the mixture below −21 °C (−6 °F): [4] Dinitrogen trioxide is only isolable at low temperatures (i.e., in the liquid and solid phases).

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.

Dinitrogen trioxide is a deep blue chemical compound with a chemical formula N 2 O 3 that is formed upon mixing equal parts of nitrogen dioxide and nitric oxide and cooling the mixture below −21 °C. It is a powerful oxidizer that is highly toxic and corrosive.

What is Nitrogen Trioxide? Nitrogen trioxide (molecular formula N2O3) is a chemical compound formed by mercury and chlorine. It is also known as dinitrogen trioxide or nitrogen sesquioxide. The compound is highly toxic and irritates the mucous membranes. Nitrogen trioxide is a blue liquid accompanied by a sharp and unpleasant chemical odour.

If 0236 moles of N2O3 are placed in a 1.52-L vessel at 25 degree C, calculate the equilibrium partial pressures of N2O3(g), Liquid N2O3 is dark blue at low temperatures, but the color fades and becomes greenish at higher temperatures as the compound decomposes to NO and NO2.

将硝酸 (密度1.30～1.35g/cm3)滴加到粉碎的As 2 O 3 上，微微加热到70°C左右，反应开始进行，生成N 2 O 3 。 制法2? 2NOHSO 4 +H 2 O→2H 2 SO 4 +N 2 O 3. 将发烟硝酸放入带有滴液漏斗和导气管的烧瓶中，通入SO 2 直到形成一个糊状体 (生成了亚硝酰硫酸)。 然后从滴液漏斗中逐滴加水则生成N 2 O 3 。 ChemicalBook 致力于为化学行业用户提供三氧化二氮的性质、化学式、分子式、比重、密度,同时也包括三氧化二氮的沸点、熔点、MSDS、用途、作用、毒性、价格 …

Dry liquid nitrogen trioxide is blue, but if moisture is present a green liquid results, owing to the mixture of wet NO2 molecules with the blue trioxide. At very low temperatures all specimens of trioxide become blue even if slightly wet because of the complete association of any wet NO2 molecules to give colourless N2O4.
