TUNGSTEN(IV) CHLORIDE - Introduction
Tungsten tetrachloride is an inorganic compound with the chemical formula WCl4. It is a colorless crystal with a strong pungent odor. The following is a description of the properties, uses, preparation and safety information of tungsten tetrachloride:
Nature:
1. Tungsten tetrachloride is a compound that can be dissolved in hydrochloric acid and carbon tetrachloride;
2. its melting point is 220 ℃, boiling point is 348 ℃;
3. four tungsten chloride can react with water to generate hydrogen chloride and tungsten oxide;
4. it is a strong oxidant, can react violently with many substances.
Use:
1. Tungsten tetrachloride is widely used in metal-organic chemical reactions, such as catalysts, catalyst preforms and catalyst carriers;
2. It can be used to prepare other tungsten compounds, such as tungsten powder, tungstic acid, etc;
3. Tungsten tetrachloride is also used in the preparation of optoelectronics and semiconductor materials.
Preparation Method:
Tungsten tetrachloride can be prepared by reacting tungsten and chlorine at high temperature. Specific steps are as follows:
1. put metal tungsten and chlorine into the reactor;
2. React at high temperature (800-900 ℃) to react tungsten and chlorine to generate tungsten tetrachloride;
3. tungsten tetrachloride is collected by process steps such as decompression and cooling.
Safety Information:
1. Tungsten tetrachloride is irritating and corrosive. Contact with skin and eyes will cause tingling and burning sensation. If necessary, rinse the affected parts with plenty of water in time and seek medical treatment immediately;
2. in the operation of four tungsten chloride should pay attention to wear personal protective equipment, such as chemical goggles, gloves, etc., to avoid inhalation and contact;
3. storage should avoid contact with air, moisture, acid and other substances, can choose a sealed container stored in a dry, cool place.
Important note: chemicals are dangerous, please use them correctly under the guidance of professionals to ensure safety!
