Tungsten(4+) tetrachloride(CAS: 13470-13-8)

Tungsten(4+) tetrachloride is a white crystalline solid with the molecular formula WCl4 and CAS number 13470-13-8. It has a molecular weight of approximately 248.9 g/mol. Tungsten(4+) tetrachloride is highly soluble in water and organic solvents. It is a weak Lewis acid and can react with bases to form tungstate salts. It is also prone to hydrolysis in aqueous solutions.

Tungsten(4+) tetrachloride is typically synthesized by reacting tungsten (W) or tungsten trioxide (WO3) with chlorine gas (Cl2) at elevated temperatures. The reaction is exothermic and requires careful control of temperature and pressure to achieve the desired yield and selectivity. Catalysts such as iron or copper can be used to improve the reaction rate and product purity.

Tungsten(4+) tetrachloride is widely used in the electronics industry for the production of tungsten metal and various tungsten-based compounds. It is also used in the production of tungsten carbide for cutting tools and wear-resistant parts. Additionally, it is employed in the synthesis of tungsten compounds for applications in polymers, sensors, and semiconductors.

When handling Tungsten(4+) tetrachloride, it is important to wear appropriate personal protective equipment (PPE), such as gloves, safety goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up using appropriate methods as outlined in the safety data sheet (SDS). Handling should be done with care to prevent chemical burns or inhalation of fumes. Always refer to the material safety data sheet (MSDS/SDS) for detailed safety information.
