Tungsten(V) chloride (WCl5)<\/a> <\/span>is a high-valence tungsten chloride composed of one tungsten atom and five chlorine atoms. It is an inorganic compound that appears as a flashing dark green crystalline solid.<\/p>\n

Physical Properties:<\/span><\/h2>\n

Chemical Formula: WCl5<\/p>\n

Molar Mass: 361.11 g\/mol<\/p>\n

Appearance: Dark green crystalline powder<\/p>\n

Melting Point: 248\u00b0C<\/p>\n

Boiling Point: 275.6\u00b0C<\/p>\n

Density: 3.875 g\/cm\u00b3 (at 25\u00b0C), with other sources reporting 3.88 g\/cm\u00b3.<\/p>\n

Solubility: Highly sensitive to moisture and water, decomposes when exposed to air. Soluble in water and hydrolyzes to form W\u2082O\u2085. Also soluble in organic solvents such as acetonitrile, benzene, chloroform, and carbon disulfide.<\/p>\n

Chemical Properties\uff1a<\/span><\/h2>\n

Stability: When heated in air, tungsten pentachloride forms tungsten oxychloride (WOCl\u2084). It decomposes in most polar solvents but is slightly soluble in non-polar solvents such as carbon disulfide.<\/p>\n

Reactivity: Reacts readily with primary amines to form amine compounds.<\/p>\n

Molecular Geometry: The WCl\u2085 molecule has a trigonal bipyramidal geometry, where the tungsten atom is bonded to five chlorine atoms via covalent sigma (\u03c3) bonds, with shorter bond lengths in the equatorial plane.<\/p>\n

Synthesis\uff1a<\/span><\/h2>\n

Reduction Method: Tungsten hexachloride (WCl\u2086) is reduced with red phosphorus at 250\u2013280\u00b0C or with hydrogen at 380\u2013400\u00b0C.<\/p>\n

Disproportionation Reaction: Can be synthesized through the disproportionation reaction of tungsten tetrachloride (WCl\u2084) or by the thermal decomposition of tungsten trichloride (WCl\u2083).<\/p>\n

Chlorination Reaction: Tungsten powder is placed in the upper layer and tungsten hexachloride (WCl\u2086) in the lower layer, with chlorine gas introduced to react with the tungsten powder to produce crude tungsten pentachloride. The crude product is then sublimed at 280\u2013300\u00b0C and condensed to obtain high-purity tungsten pentachloride.<\/p>\n

Applications:<\/span><\/h2>\n

Synthesis of Other Tungsten Compounds: WCl5 is used to synthesize other tungsten compounds, such as tungsten hexachloride (WCl\u2086), tungsten tetrachloride (WCl\u2084), tungsten powder, and tungsten carbide powder. These compounds have various applications, including tungsten powder for tungsten materials and alloys, and tungsten carbide powder for hard alloys.<\/p>\n

Catalyst and Organic Compound Synthesis: WCl5 is also used in the synthesis of catalysts and organic compounds.<\/p>\n

Quality Control<\/span><\/h2>\n

VI HALBLEITERMATERIAL GmbH (VIMATERIAL<\/a><\/span>) implements a rigorous quality assurance system, conducting strict quality control across the entire production chain, reworking defective products, and releasing each batch only after passing detailed specification tests. The company adheres to the highest standards in R&D, production, shipping, and customer service, investigates deviations via the 8D procedure, complies with REACH and ASTM standards, ensures batch consistency and traceability, and is committed to building a socially responsible supply chain to protect human health and the environment.<\/p>\n

Storage and Transportation\uff1a<\/span><\/h2>\n

Storage Conditions: Due to its sensitivity to moisture and water, tungsten pentachloride (WCl5) should be stored in a dry, cool, and well-ventilated place, avoiding contact with air. It is typically stored in sealed tubes or under an inert gas atmosphere.<\/p>\n

Transportation Precautions: During transportation, the packaging should remain intact and sealed, complying with relevant hazardous material transportation regulations. It should not be transported with moisture-sensitive substances or oxidizers.<\/p>\n","protected":false},"excerpt":{"rendered":"
