Ethane, 1,1,1,2,2-pentabromo- - Introduction
pentabromoethane is an organic compound with the chemical formula C2Br5H. The following is a detailed description of the nature, use, preparation and safety information of the pentabromoethane:
Nature:
1. Appearance: The pentabromoethane is a colorless or light yellow liquid with a pungent odor.
2. density: the density of pentabromoethane is larger, heavier than water.
3. Solubility: pentabromoethane and organic solvents such as alcohol, ether and other miscible, but almost insoluble in water.
Use:
1. Optical field: pentabromoethane can be used as semiconductor materials for light-emitting diodes (LEDs).
2. laboratory: pentabromoethane can be used as brominating reagent, mordant of mercury bromide and other organic synthesis reaction reagent.
Preparation Method:
pentabromoethane can be obtained by reacting brominated ethane with metallic magnesium. The specific preparation steps are as follows:
1. The brominated ethane is mixed with dry isopropanol and reacted at low temperature to form pentabromoethane.
2. The resulting pentabromoethane is filtered and washed to obtain the pure product.
Safety Information:
1. pentabromoethane has a pungent odor, contact with skin, eyes or respiratory system may cause irritation, direct contact should be avoided.
2. pentabromoethane is toxic to aquatic organisms and should be avoided from entering the water body.
3. in the use of pentabromoethane should pay attention to good ventilation conditions, avoid inhalation of its steam.
4. storage should be placed in a closed container, away from the fire and oxidant, to avoid leakage or combustion.
Please note that pentabromoethane is a toxic compound and should be thoroughly understood and followed before use.
