Sodium hypochlorite temperature

In the chlor-alkali production process, it is appropriate to keep the temperature of sodium hypochlorite between 30 and 40 degrees Celsius. This is because: 1. Too low a temperature will cause the hypochlorite in the sodium hypochlorite solution to crystallize, affecting subsequent production processes ； 2. Excessively high temperatures can cause sodium hypochlorite to decompose, reducing its bactericidal effect and stability ； 3. At temperatures of around 30–40°C, sodium hypochlorite decomposes most readily, thereby releasing active chlorine that exerts a bactericidal effect. Therefore, maintaining the temperature of sodium hypochlorite between 30 and 40 degrees Celsius ensures effective sterilization without affecting production operations. .

In the chlor-alkali production process, it is generally appropriate to keep the temperature of recycled sodium hypochlorite between 30°C and 35°C. Excessively high temperatures can cause sodium hypochlorite to decompose, releasing oxygen and increasing system pressure, which may lead to safety accidents ； It will also reduce the chlorine content in the solution as well as the efficiency of the alkaline solution. On the other hand, too low a temperature affects the efficiency of the electrolyzer and the quality of the electrolytic products, while also increasing the energy consumption for electrolysis. Therefore, by properly controlling the temperature of circulating sodium hypochlorite, the safe, stable, and efficient operation of chlor-alkali production can be ensured. Specific adjustments should be made based on the actual situation, taking into account factors such as the process flow, equipment performance, and the condition of the raw materials.

During the production of sodium hypochlorite, it is advisable to keep the temperature of the reaction system at a low level; this ensures effective absorption of chlorine gas while also reducing the amount of chlorate that decomposes.
