FAQ

What are the physical and chemical properties of Sodium Hexafluoroaluminate (CAS: 15096-52-3)?

Sodium hexafluoroaluminate (CAS: 15096-52-3) is a white crystalline solid with a high molecular weight and low solubility in water. It is highly reactive with moisture and organic compounds. It has a molecular weight of approximately 146.97 g/mol and is not soluble in water but soluble in hydrofluoric acid. It is known for its strong basicity and reactivity with alcohols and amines.

How is Sodium Hexafluoroaluminate (CAS: 15096-52-3) typically synthesized?

Sodium hexafluoroaluminate (CAS: 15096-52-3) is typically synthesized by the reaction of aluminum fluoride with sodium fluoride, producing a product that is then purified. This process involves the use of a high vacuum to remove excess fluoride gases, and the product is often recrystallized to obtain a pure form. The synthesis yields a highly reactive compound that is often used in specialized applications.

What industries use Sodium Hexafluoroaluminate (CAS: 15096-52-3)?

Sodium hexafluoroaluminate (CAS: 15096-52-3) is used in various industries including pharmaceuticals, where it is used as a reagent in organic synthesis, and in the production of certain organic compounds. It is also used in the synthesis of sensors and semiconductors due to its strong reactivity and specific chemical properties.

What precautions should be taken when handling Sodium Hexafluoroaluminate (CAS: 15096-52-3)?

Sodium hexafluoroaluminate (CAS: 15096-52-3) requires specific handling precautions due to its strong reactivity.
