Sodium chlorate is a cornerstone of modern industrial chemistry, with its primary application being the production of chlorine dioxide (ClO₂), a powerful oxidizing agent. According to the National Institute of Standards and Technology (NIST), chlorine dioxide is widely used in the pulp and paper industry for bleaching processes, accounting for approximately 95% of sodium chlorate's industrial use. Below are key applications:
The largest application of sodium chlorate is in the production of chlorine dioxide, which is used to bleach wood pulp. This process enhances the brightness of paper while minimizing environmental impact compared to traditional methods.
Sodium chlorate serves as a precursor for other chlorate compounds through salt metathesis reactions. It is also used in the industrial production of perchlorates via electrolysis, as noted in NIST's research on chemical manufacturing processes.
Chlorine dioxide, derived from sodium chlorate, is employed in water treatment to disinfect and remove contaminants. Its effectiveness in eliminating bacteria and organic matter makes it a preferred choice for municipal and industrial water systems.
In agriculture, sodium chlorate is used as a herbicide to control weeds. However, its use is regulated due to potential environmental and health risks, underscoring the importance of proper handling and disposal.
