MANUFACTURING PROCESS (OCCIDENTAL)

Sodium hypochlorite (soda bleach) solutions can be prepared by reacting chlorine with solutions of

caustic soda, soda ash (sodium carbonate), or a combination of caustic soda and soda ash. Soda

ash processes produce less stable sodium hypochlorite solutions. For that reason, only the

caustic soda processes will be discussed in this handbook.

Potassium hypochlorite, another bleach product, can be produced with the same equipment for

production of soda bleach solutions.

As previously stated, chlorine will react with a caustic soda solution to produce sodium

hypochlorite according to the following equation:

PRODUCT SPECIFICATION

Description: Sodium hypochlorite is a clear pale greenish yellow solution.

Density: g/cm3

 at 20°C 1,23 Min

Available Chlorine when despatched (Cℓ2): % m/v 15 Min

Sodium Hydroxide (NaOH): % m/vℓ 1,5 Max

Stability: When the solution is kept in the dark at a temperature of 20°C to 25°C and tested on the

14th day after date of despatch the available chlorine content shall not be less than 13% m/v.

Nevertheless all hypochlorite solutions decompose slowly on standing with the formation of sodium

chlorate and sodium chloride with the evolution of some oxygen.
