Chlorine does not occur in nature in elemental form. Chlorine is therefore produced on an industrial scale at Donau Chemie using the environmentally friendly membrane process known as chlor-alkali electrolysis of a sodium chloride solution. The by-products are caustic soda and hydrogen.

2 NaCl + 2 H2O → 2 NaOH + Cl2 + H2

Chlorine is used in the manufacture of many products such as bleaching agents, PVC or hydrochloric acid. Chlorine is also used in drinking water disinfection or for bathing water treatment in swimming pools.

Chlorine is available at Donau Chemie in steel pressure vessels such as tank wagons up to approx. 64 t, steel drums up to approx. 1000 kg and steel cylinders of 50 kg or 65 kg.

But chlorine also makes an important contribution to energy efficiency. Chlor-alkali chemicals are found in insulating materials, in the production of renewable energies, in environmentally friendly heat pumps and much more. Chlor-alkali production is also linked to the production of hydrogen, an important energy carrier and chemical ingredient for the future.

These chlor-alkali based products could also play an important role in meeting European sustainability goals under the Green Deal. 

The use of Chlor-alkali chemistry for purifying water has been effective for over 100 years. A shortage of safe drinking water is a major factor in the recurring outbreak of diseases. Chlor-alkali disinfectants play a critical role in ensuring clean water.

Chlorine has immense importance in various aspects of our lives. It is a versatile chemical component that contributes significantly to improving health, hygiene, industry and quality of life. You can find more videos on the different areas of application        here
