13 Uses of Sodium Hydroxide (NaOH) One Should Know

Witryna8 maj 2024 · The name comes from the two main products of the process, chlorine and the alkali, sodium hydroxide (NaOH). Therefore, one of the main uses of the chlor-alkali process is the production of NaOH. As described earlier, the equation for the chlor-alkali process, that is, the electrolysis of NaCl, is as follows: WitrynaNitric Acid Process Presently in the United States there is only one plant producing chlorine by the nitric acid process. However, it is worthy of note since it has a considerable chlorine capacity. There are two main considerations for using this process: (1) an outlet for NaNO3, which is produced as a co-product with chlorine; and (2) a WitrynaThe chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions.
