Chloralkali – this is about producing chlorine and an alkali (soluble base, sodium hydroxide) on an industrial scale.
Indust. Prep. of Chlorine
This method to prepare chlorine is an electrolytic process.
This simply means that elelctricity is used to make a chemical reaction!
Electrical energy is converted to chemical energy.
New chemical compounds are thus formed.
Simply Stated:
:: this involves the electrolysis of brine – (sodium chloride solution)
:: an electric current is sent through the salt solution
What are the industrial methods for producing chlorine?
1. Mercury Cell
- liquid mercury stream
- mercury is highly volatile
- poisonous
2. Diaphragm Cell
- asbestos is involved
- health risk
3. Membrane Cell (most modern and popular)
