6/17

The development of sodium chlorite as an

industrial chemical began in 1921when E.

Schmidt found that cellulosic fibers could

be purified with chlorine dioxide without

being appreciably damaged.

Unfortunately, chlorine dioxide gas isextremely explosive at high concentrations.

These discoveries prompted researchers to

look for safe and economical ways to deliver

chlorine dioxide for bleaching purposes.

The first company to introduce sodiumchlorite for this purpose was the Mathieson

Chemical Corporation.

In 1960, sodium chlorite became the

standard material for continuous bleachingoperations in the United States, replacing

hydrogen.

The Manufacturing ProcessThe Manufacturing Process

yWhile a variety of chlorites are

available, sodium chlorite is the only

one produced commercially.

y It is sold in solution or as a solid.

yThe technical grade is made up of

about 80% sodium chlorite and the

rest is sodium chloride.


11/17

yLarge scale production is based on a

reaction of chlorine dioxide in a sodium

hydroxide solution.

y Sodium chlorite is manufactured in

three phases

chlorine dioxide production,

sodium chlorite generation,

and recovery.

yAs a textile-bleaching agent, sodium

chlorite is effective with various

fibersy It can be used on Natural as well as

man made fibers.

y Sodium chlorite is also used for various

industrial applications.

y It controls microbial contamination in

industrial cooling systems and towers.

y It is used in place of chlorine in

industrial ammonia plants because it

does not react negatively withammonia.



15/17

Since it is an oxidizer, it is often a part of

flue gas scrubber systems. Food-

processing companies use it forwashing fruits and vegetables because

it is a fungicide.
