Deacon Process

Name:
Deacon Process
Detailed information:
A method of converting hydrogen chloride to chlorine by oxidation of hydrogen chloride with oxygen at 400–500C over a copper-salt catalyst, 2HCl + O → Cl₂ + H₂O. It is a means of producing chlorine without caustic and of utilizing the large amounts of by-product hydrogen chloride from the chlorination of organic compounds. When conducted in the presence of an organic compound that reacts with the chlorine formed, it is known as oxychlorination, e.g., CH₂═CH₂ + 2HCl + O → CH₂ClCH₂Cl + H₂O.
