Chlorite bleaching corrosion

The rate of chlorite bleaching increases as pH decreases, but only between pH 2 and 9 is the rate proportional to the concentration of chlorous acid present in solution. At low pH values, evolution of the noxious and corrosive gas chlorine dioxide increases. In practice it is necessary to keep the pH above 3 in order to minimise the formation of chlorine dioxide. It is necessary to monitor the pH during chlorite bleaching because acid is liberated by the... 

Activator and Stabilizer for Sodium Chlorite Bleaching POLYRON CB is an additive used in sodium chlorite bleaching in order to activate the process without the addition of acid, to prevent odor nuisance, corrosion, and to increase the whiteness. ... 

Sodium Chlorite bleaching assistant. Activates and stabilizes bleach bath to increase whiteness and reduce odor problems. Contains corrosion inhibitors. 

X-Tan Special C. [Sybron] Supi esses chlorine release in chlorite bleaching iwevents metal corrosion. 

POLYRON CB also contains highly effective corrosion inhibitors. POLYRON CB enables a highly effective bleaching process without side-reactions, so that excess amounts of chlorite are not necessary. 

CNC CHLORITE is a modified sodium chlorite product designed to give the excellent bleaching with fiber protection that is normal for sodium chlorite but with the added advantage of anti-corrosion properties to stainless steels and reduced hazards in handling. 

Sodium Chlorite 25K Liquid, 50K and 90K Powder. Bleaching and stripping agents containing corrosion inhibitiors. 

Chlorite odor and corrosion inhibitor. Minimizes odor and corrosion in sodium chlorite stripping and bleaching. 

Scouring and bleaching of jute with sodium chlorite with an acceptable whiteness can be achieved, but the process is a time consuming two step process. Moreover, sodium chlorite is metal corrosive and health hazardous. 

Titanium is fully resistant to solutions of chlorites, hypochlorites, chlorates, perchlorates, and chlorine dioxide. Titanium equipment has been used to handle these chemicals in the pulp and paper industry for many years with no evidence of corrosion. Titanium is used today in nearly every piece of equipment handling wet chlorine or chlorine chemicals in a modern bleach plant, such as chlorine-dioxide mixers, piping, and washers. In the future it is expected that these applications will expand to include the use of titanium in equipment for ClOj generators and wastewater recovery.
