Usage

Description

Beryllium nitrate, also known as beryllium dinitrate, is an ionic beryllium salt of nitric acid with the chemical formula Be(NO3)2. It is very soluble in water and forms colorless, deliquescent crystals. Beryllium nitrate is a white to pale yellow crystalline solid, and its tetrahydrate form has a CAS number of 13597-99-4.

Uses

Used in Chemical Industry:
Beryllium nitrate is used as a chemical reagent for various applications, including the introduction of beryllium oxide into materials used in incandescent mantles.
Used in Manufacturing Gas Lantern Mantles:
Beryllium nitrate is used as a hardening agent for mantles on gas lanterns, providing structural integrity and enhancing the performance of the mantles.
Physical Properties:
Beryllium nitrate trihydrate (CAS number = 7787-55-5) forms slightly yellow crystals with a vapor pressure of 49.8 mm Hg at 25°C. Its melting point is 60.5°C, and it decomposes completely at 102.3°C. The enthalpy of vaporization is 37.72 kJ/mol, and its boiling point is 83°C at 760 mm Hg where it becomes anhydrous.
Chemical Properties:
Beryllium nitrate is a white to faintly yellowish, deliquescent mass. It is soluble in water and alcohol. 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.
Safety Information:
Beryllium nitrate is a tumorigen, mutagen, and reproductive effector in rats and, presumably in humans. It is important to handle this compound with care and follow safety protocols to minimize exposure and potential health risks.

Preparation

Anhydrous beryllium nitrate has been prepared by the reaction of anhydrous beryllium chloride with an ethylacetate-dinitrogen tetroxide mixture to give Be(NO3)2 · 2N2O4 [Addison and Walker 1963]. When heated above 50 °C (120 °F) in a vacuum, oxides of nitrogen are evolved, leaving anhydrous beryllium nitrate. The anhydrous salt is stable to approximately 125 °C (255 °F), when a sudden decomposition occurs to give nitrogen tetroxide and a volatile compound that separates from the gas phase as colorless Be4O(NO3)6 crystals. These crystals are slowly hydrolyzed when added to water.

Hazard

Very toxic. Oxidizing material, dangerous fire risk.

Hazard

Beryllium nitrate is a toxic chemical,like all other beryllium compounds. It is also an irritant in small doses. When burned, it gives off irritating or toxic fumes. However, when massive short-term exposure occurs, acute pneumonitis can set in, but symptoms do not manifest themselves for 3 days.

Safety Profile

Confirmed carcinogen. Poison byintraperitoneal, intravenous, and subcutaneous routes.Experimental reproductive effects. When heated todecomposition it emits very toxic fumes of BeO and NOx.

Synthesis

Beryllium nitrate can be prepared by reacting beryllium hydroxide in nitric acid. Be(OH) + 2 HNO → Be(NO) + 2 HO
