ethylenebis(indenyl)zirconium(iv) dichloride - Introduction
Dichloro[rac-ethylenebis(indenyl)] The zirconium(IV) is an organometallic compound having a chemical formula of C26H20Cl2Zr in which a zirconium atom is present in a valence of 4. The following are some of the properties, uses, preparation and safety information about the compound:
Nature:
- Dichloro[rac-ethylenebis(indenyl)]zirconium(IV) is a colorless crystal, soluble in non-polar solvents like benzene.
-It is relatively stable at high temperatures, but may gradually decompose in the air.
-The compound has good thermal stability and catalytic activity.
Use:
- Dichloro[rac-ethylenebis(indenyl)]zirconium(IV) is an important zirconium halide catalyst.
-It is widely used in catalytic processes such as olefin polymerization, olefin copolymerization and olefin insertion polymerization.
-In addition, it can also be used as a catalyst for the preparation of zirconium-containing organometallic polymers and metal organic chemical reactions.
Preparation Method:
- Dichloro[rac-ethylenebis(indenyl)]zirconium(IV) can be prepared by reacting zirconium(IV) chloride with bis-indenyl ethylene.
-The reaction is usually carried out under an inert atmosphere, and the desired product is obtained through purification steps.
Safety Information:
- Dichloro[rac-ethylenebis(indenyl)] The toxicity of zirconium(IV) is usually low, but because it is a metal organic compound, it is still necessary to pay attention to safe operation.
-During the operation, avoid direct contact with skin and eyes, and ensure that the work area is well ventilated.
-Wear appropriate personal protective equipment such as laboratory gloves, goggles, and protective clothing when using the compound.
Please note that chemical experiments and operations should be carried out under suitable equipment and conditions, and follow relevant safe operating procedures and guidelines.
