22411-22-9 - Introduction
Hafnium n-butoxide, the chemical formula Hf(OH)4, is also known as hafnium n-butoxide. The following is a description of its nature, use, formulation and safety information:
Nature:
1. hafnium n-butoxide is a white solid, soluble in water and organic solvents.
2. It is a hydrophilic compound with strong alkalinity.
3. Stable in the air, but easy to damp.
Use:
1. Hafnium n-butoxide is mainly used as a catalyst in organic synthesis reactions, especially in the mitochondrial esterification reaction of Bartona.
2. It is also applied to the selective oxidation of active hydrogen in organic molecules.
Preparation Method:
A common method for preparing n-hafnium butoxide is to react n-butanol with a chloride of hafnium to generate hafnium hydroxide. The chemical equation of the reaction is as follows:
HfCl4 4C4H9OH → Hf(OH)4 4C4H9Cl
Safety Information:
Hafnium n-butoxide is a relatively safe compound. However, during use, general laboratory safety regulations need to be observed, such as wearing appropriate protective gloves and goggles. At the same time, avoid direct contact with skin and eyes, and maintain good ventilation conditions. If splashed into the eyes or skin, rinse immediately with water and seek medical help.
