Abstract
In the production of chlorinated hydrocarbons by contacting a molten salt mixture of the higher and lower chloride of a multivalent metal, such as a mixture of cuprous and cupric chloride, with molecular oxygen to effect oxidation to the oxychloride, followed by use of the oxidized salt for the production of chlorinated hydrocarbons, the quantity of carbon dioxide vented from the system is determined, and oxygen introduction is decreased in response to increases in vented carbon dioxide to decrease oxychloride concentration and limit carbon dioxide production.
