Chlorine can be manufactured by the electrolysis of a sodium chloride solution , which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2). These two products, as well as chlorine itself, are highly reactive.
The chloralkali process has been in use since the 19th century and is a primary industry in the United States, Western Europe, and Japan. [4] [5] It has become the principal source of chlorine during the 20th century. [6]
Original – A membrane cell process for chloralkali production Reason Complicated diagram to support a discussion with a lot of chemical equations and mass transfer and charge balance. Huge industry (important article). Support work on chlorine Articles in which this image appears Chloralkali process, Chlorine, Chlorine production
Under steady state conditions the chloride process is a continuous cycle in which chlorine changes from the oxidized state to the reduced state and reverse. The oxidized form of the chlorine is molecular chlorine Cl 2, the reduced form is titanium tetrachloride (TiCl 4). The oxidizing agent is molecular oxygen (O 2), the reducing agent is coke ...
Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...
The first type, shown on the right and left of the diagram, uses an electrolyte of sodium chloride solution, a graphite anode (A), and a mercury cathode (M). The other type of cell, shown in the center of the diagram, uses an electrolyte of sodium hydroxide solution, a mercury anode (M), and an iron cathode (D). The mercury electrode is common ...
The process of electrochlorination is a simple application based on the chloralkali process (in an unpartitioned cell). It is the electrolysis of saltwater to produce a chlorinated solution. The first step is removing any solids from the saltwater. Next, the saltwater streams through an electrolyzer cell's channel of decreasing thickness.
In 1884 Chemischen Fabrik Griesheim of Germany developed another chloralkali process which entered commercial production in 1888. [33] Elemental chlorine solutions dissolved in chemically basic water (sodium and calcium hypochlorite) were first used as anti-putrefaction agents and disinfectants in the 1820s, in France, long before the ...
