Beryllium chloride, also known as beryllium dichloride in IUPAC nomenclature, is an inorganic compound of beryllium and chloride represented by the chemical formula BeCl2 [1]. It can attract and hold water from the surrounding environment (hygroscopic compound) and dissolves well in several polar solvents [2].

Beryllium Chloride Formula

How is Beryllium Chloride Prepared

It is synthesized by the reaction of beryllium with chlorine at a temperature of about 250 °C, which is represented by the following equation [4]:

Be Cl2 → BeCl2

When beryllium oxide reacts with chlorine in the presence of carbon at a temperature of about 700-900 °C, it undergoes carbothermal reduction to yield carbon monoxide and beryllium chloride [5]:

BeO Cl2 C → BeCl2 CO

BeCl2 can also be produced by the reaction of beryllium with a diluted solution of hydrogen chloride:

Be 2HCl → BeCl2 H2

Reactions with Other Compounds

Beryllium Chloride with Silver Nitrate

Beryllium chloride reacts with silver nitrate dissolved in water, to form silver chloride powder and an aqueous solution of beryllium nitrate:

BeCl2 2AgNO3 → Be(NO3)2 2AgCl

Structure of Beryllium Chloride

What is Beryllium Chloride Used for

  • It is a catalyst as well as a chemical intermediate for several beryllium compounds [5].
  • Used as a raw material used during the electrolytic extraction of beryllium [6].

Is It Safe

Beryllium chloride causes acute toxicity if inhaled, swallowed, or exposed through the skin. It results in skin corrosion, allergic skin reaction, eye and respiratory tract irritation [1]. It is known to be a carcinogen in humans and may cause organ toxicity, including lung cancer through repeated exposure [1].
