<p>The present invention provides a method for producing a low-salt aqueous sodium hypochlorite solution at a high yield. The method includes the steps of: (1) providing 30-50 wt% of a sodium hydroxide solution to a reaction tank; (2) executing a chlorination reaction at a reaction temperature of 20-50°C by inserting chlorine gas, obtained by diluting the provided sodium hydroxide with inert gas in the reaction tank; and (3) obtaining the sodium hypochlorite solution by separating and removing byproduct sodium chloride, precipitated in step (2), from a reaction solution.</p> |
