Оксихлорид циркония

Description

Zirconium oxychloride (anhydrous form) is an inorganic zirconium(IV) salt of the composition ZrOCl2, also known as zirconyl chloride. In the supplier dump for this catalog item, the safety data sheet and numerical physical and chemical parameters are not given; Molecular weight and physical properties are based on publicly available reference data in CAS 7699-43-6. The chemical nature of the substance is close to zirconium oxychloride octahydrate (a separate catalog item, CAS 13520-92-8), differing from it in the absence of water of crystallization.

Basic Attributes

• CAS No.: 7699-43-6
• Chemical formula: Cl2OZr
• Molecular weight (anhydrous form): 178.12 g/mol

Physico-chemical characteristics

• Appearance: white or yellowish silky crystals, odorless
• Density: 1.91 g/cm3
• Octahydrate loses water of crystallization at 210 °C, decomposes at 400 °C
• Solubility: soluble in water, alcohol and ether; slightly soluble in hydrochloric acid; aqueous solutions are acidic

Scope of application

It is used for the production of pigment mordants and improving the properties of colored varnishes of acid and basic dyes, as well as in the compositions of deodorants and antiperspirants, water-repellent impregnations, dye precipitants, catalysts and as raw materials for the production of many other zirconium compounds.

• pigment mordants and colored varnishes of acid and basic dyes
• deodorants and antiperspirants (aluminum-zirconium complexes)
• water-repellent impregnations for textiles
• dye precipitant and organic synthesis catalyst
• raw materials for the production of other industrial zirconium compounds
• precursor for obtaining oxide and other zirconium salts in laboratory practice

Advantages

The anhydrous form differs from the octahydrate (a separate catalog item, CAS 13520-92-8) in the absence of water of crystallization, which makes it a more concentrated source of zirconium in synthesis, which requires precise control of the moisture introduced into the reaction.

Storage and transportation conditions

Store in a tightly closed container in a dry place, since the substance is hygroscopic and tends to absorb moisture and transform into hydrate forms. General precautions for zirconium halide salts include the use of gloves and safety glasses due to the formation of an acidic environment when dissolved in water.

Delivery form and quality

Since the supplier's passport for this catalog item does not contain a numerical block of characteristics (density, temperatures, hazard codes), when purchasing a batch, it is recommended to separately request a current certificate of analysis (COA) and safety data sheet (SDS) from the specific manufacturer. The physical constants given here (molecular weight 178.12 g/mol, density 1.91 g/cm3, octahydrate transition temperatures) refer to publicly known reference data for this CAS number and not to a specific batch from the echemi supplier. The absence of passport data in the dump does not mean the lack of regulatory status of the substance - CAS 7699-43-6 is widely represented in international chemical registers.
