Tetraethoxyhafnium - Introduction
Hafnium(IV) ethoxide(Hafnium(IV) ethoxide) is an inorganic compound with the chemical formula Hf(OC2H5)4. The following is a description of the nature, use, preparation and safety information of Hafnium(IV) ethoxide:
Nature:
- Hafnium(IV) ethoxide is a colorless liquid with a chili-like pungent odor at room temperature.
-It is soluble in many organic solvents, such as ethanol, dimethylformamide and dichloromethane.
- Hafnium(IV) ethoxide is easy to hydrolyze, and generates ethanol and hafnium hydroxide in case of water.
Use:
- Hafnium(IV) ethoxide are commonly used as precursors for solvents and catalysts.
-It can be used for esterification, acylation, condensation and dehydration reactions in organic synthesis.
- Hafnium(IV) ethoxide are also used in the fields of optical coatings, conductive films and ceramic materials.
Preparation Method:
- Hafnium(IV) ethoxide can be obtained by reacting metallic hafnium with ethanol in the presence of oxygen.
-The reaction is usually carried out under an inert atmosphere to avoid reaction with water vapor in the air.
Safety Information:
- Hafnium(IV) is ethoxide irritating, and contact with skin and eyes can cause irritation and burns.
-Avoid inhaling its vapor or dust during use to avoid damage to the respiratory system.
-Wear appropriate personal protective equipment such as gloves, protective eyewear and laboratory coats when handling Hafnium(IV) ethoxide.
- Hafnium(IV) ethoxide should be stored in dry, sealed containers, away from fire and oxidizing agents.
