Zirconium tetrachloride is an important inorganic compound.
The following is a detailed introduction to zirconium tetrachloride:
1. Basic information Chinese name: Zirconium tetrachloride
English name: Zirconium tetrachloride , Zirconium chloride (IV) English alias: Zirconium (4+) tetrachloride; ZrCl4
CAS number: 10026-11-6
Molecular formula: ZrCl4
Molecular weight: 233.036
2. Physical properties Properties: White shiny crystals or powder, easy to deliquesce.
Melting point: 437℃ (2533.3kPa)
Boiling point: 331℃ (sublimation)
Relative density (water = 1): 2.80 (another saying is 2.083)
Saturated vapor pressure: 0.13kPa (190℃)
Solubility: Soluble in cold water, ethanol, ether and concentrated hydrochloric acid, insoluble in benzene, carbon tetrachloride, carbon disulfide.
3. Chemical properties Stability: Stable at room temperature, but will react violently with water to form stable zirconium oxychloride hydrate (ZrOCl2·8H2O). Incompatible materials: water, amines, alcohols, acids, esters, ketones, etc. Conditions to avoid contact: humid air.
4. Synthesis method Carbon reduction method: Zircon (ZrSiO4) is mixed with carbon and then reduced at high temperature to form zirconium carbide (ZrC). Zirconium carbide then reacts with chlorine to form zirconium tetrachloride. Electrolysis method: Zircon reacts with sodium hydroxide to form sodium zirconate, and then sodium chloride solution is electrolyzed to form metallic sodium and zirconium tetrachloride.
5. Main uses Analytical reagent:
Zirconium tetrachloride can be used as an analytical reagent for quantitative analysis of various chemical reactions. Organic synthesis catalyst: In organic synthesis, zirconium tetrachloride can be used as a catalyst to accelerate the reaction.
Waterproofing agent: Zirconium tetrachloride can be used for waterproofing of textiles and other materials.
Tanning agent: In the leather manufacturing process, zirconium tetrachloride can be used as a tanning agent to make the leather softer and more durable.
6. Storage and Transportation Storage: Zirconium tetrachloride should be stored in a cool, dry, well-ventilated warehouse, away from fire and heat sources. The package must be sealed to prevent moisture. At the same time, it should be stored separately from acids, amines, alcohols, esters, etc. to avoid mixed storage. Transportation: During transportation, the packaging should be intact and sealed, and the relevant dangerous goods transportation regulations should be followed.
7.Safety Information Risk Terms:
R14 (Reacts violently with water); R22 (Harmful if swallowed); R34 (Causes burns). Safety Instructions: S8 (Keep container dry); S26 (After contact with eyes, rinse immediately with plenty of water and seek medical advice); S36/37/39 (Wear appropriate protective clothing, gloves and goggles or mask); S45 (In case of accident or if you feel unwell, seek medical attention immediately).
