• Description: Beryllium nitrate is said to have the molecular formula of Be(NO3)2 and the molecular weight of grams per mole. It is very soluble in water. It could be prepared by the action of nitric acid on beryllium carbonate, oxide or hydroxide: BeCO3 + 2HNO3 ? Be(NO3)2 + CO2 +H2O Be(OH)2 + 2HNO3 ? Be(NO3)2 + 2H2O It is described as Be(NO3)2·4H2O, a compound that forms colorless, deliquescent crystals that are soluble in water, and used to introduce beryllium oxide into materials used in incandescent mantles. However, in view of recent developments concerning the behavior of the Be3+ cation in solution, the more likely reactions are: BeCO3 + 2HNO3 ? Be(OH)NO3 + CO2 + 1/2H2O Be(OH)2 + 2HNO3 ? Be(OH)NO3 + 3/2H2O
• Physical properties: DTA analysis of the tetrahydrate showed that it dissolves in its own waters of hydration at about 60.4°C. Heating above 101°C causes decomposition with loss of water and oxides of nitrogen plus formation of the oxide. The decomposition is complete at 250°C. Thermal decomposition of these salt hydrates occurs by release of nitric acid which then breaks down to form the nitrogen oxides, rather than break down of the nitrate anion itself. The anhydrate has been prepared by the reaction of beryllium chloride with N2O4 dissolved in ethylacetate. If heated in a vacuum above 50°C, the product, Be(NO3)2·2N2O4, evolves oxides of nitrogen to produce the anhydrate. The tetrahydrate has a CAS number of 13597-99-4 and molecular weight is grams per mole. Anhydrous beryllium nitrate is a white to pale yellow crystalline solid. Beryllium nitrate trihydrate (CAS number = 7787-55-5) forms slightly yellow crystals with a vapor pressure 49.8 mm Hg at 25°C. Its melting point is 60.5°C and it decomposes completely at 102.3°C. Its Enthalpy of vaporization = 37.72 kJ/mol and its boiling point is 83°C at 760 mm Hg where it becomes anhydrous. Beryllium nitrate is a tumorigen, mutagen and reproductive effector in rats and, presumably in humans. Beryllium metal dissolves readily in nonoxidizing acids such as HCl and H2SO4, but not in nitric acid as this forms the oxide (this behavior is similar to that of aluminum metal). Beryllium, again similarly to aluminum, dissolves in warm alkali to form the beryllate anion, Be(OH)42-, and hydrogen gas. Beryllium nitrate, also known as beryllium dinitrate, is an ionic beryllium salt of nitric acid with the chemical formula Be(NO).Each formula unit is composed of one Be2+ cation and two NO-anions.
• Uses: Beryllium nitrate is used as a hardening agent for mantles on gas lanterns. Chemical reagent, gas-mantle hardener.
