Industrial Grade 99% Sodium Hydroxide Caustic Soda High Purity Flake Sodium Hydroxide CAS 1310-73-2 Food Grade Caustic Soda Solid Alkali Raw Material

Product Description

Product Description:
Sodium hydroxide, also known as caustic soda, lye, or caustic alkali, is an inorganic compound with the chemical formula NaOH and a relative molecular weight of 39.9970. Sodium hydroxide is strongly alkaline and highly corrosive. It is a white solid, commonly found in flake, granular, and liquid forms. It is hygroscopic and highly hygroscopic; when exposed to air, it absorbs moisture and reacts with carbon dioxide to form sodium carbonate. It is readily soluble in water, releasing a large amount of heat; its aqueous solution is strongly alkaline. It is soluble in ethanol and glycerol, but insoluble in ether and acetone. In industrial production, it is used to manufacture plastics, dyes, adhesives, acid neutralizers, compounding masking agents, precipitants, precipitation masking agents, color developers, saponifying agents, peeling agents, and detergents. It is also used in bauxite dissolution and petroleum desulfurization processes. Its strong alkalinity makes it suitable for use as a bleaching agent, drain cleaner, and water treatment agent in the cleaning industry. It is also used as a desiccant in chemical experiments, making its applications very wide-ranging.7

Our Process:
In terms of production process, we use refined saturated brine entering the anode chamber and pure water (with a certain amount of NaOH solution added) entering the cathode chamber. After energization, H2O discharges on the cathode surface to generate H2, while Na+ passes through the ion-exchange membrane from the anode chamber into the cathode chamber. At this point, the catholyte introduced into the cathode chamber contains NaOH. Cl- discharges on the anode surface to generate Cl2. The dilute brine after electrolysis is extracted from the anode chamber and can be recycled after adding salt to increase its concentration.

The reason for injecting pure water instead of NaCl solution into the cathode chamber is that the reaction in the cathode chamber is 2H+ + 2e- = H2↑; while Na+ can pass through the ion-exchange membrane to reach the cathode chamber to generate NaOH solution. However, at the beginning of electrolysis, to enhance the conductivity of the solution without introducing new impurities, a certain amount of NaOH solution is often added to the water in the cathode chamber.

Our Strengths:
1. High-quality caustic soda, meeting the quality requirements of high-purity caustic soda in industries such as chemical fiber and pharmaceuticals.

2. Reduced energy consumption. 3. Pollution-free: The ion-exchange membrane method for chlor-alkali production produces no waste, avoiding the mercury pollution of the mercury process and the asbestos waste of the diaphragm process.

4. High-purity chlorine gas: Typically >99% purity, making it an excellent raw material for organochlorine production.

5. High-purity hydrogen gas: Typically >99% purity, allowing direct use in applications requiring high-purity hydrogen.
