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].
