Sodium hydroxide is indispensable in multiple sectors:
- Aluminum Surface Treatment: Used for cleaning and etching aluminum profiles to improve adhesion and surface quality. The chemical reacts with the aluminum oxide layer, preparing the surface for coating or anodizing.
- Water Treatment: Regulates pH and removes heavy metals and impurities. Caustic soda neutralizes acidic water and facilitates the precipitation of metals, ensuring safe drinking water and industrial effluent treatment.
- Chemical Manufacturing: Acts as a base catalyst in producing various chemicals and detergents. Sodium hydroxide is essential in saponification reactions to produce soaps and in the manufacture of synthetic fibers.
- Pharmaceuticals: Used in drug synthesis and pH adjustment. Its purity and consistency are critical for producing active pharmaceutical ingredients (APIs).
- Paper and Pulp Industry: For pulping and bleaching processes. Caustic soda breaks down lignin and other organic materials, enhancing paper quality.
- Food Industry: Used in food processing and cleaning. Sodium hydroxide is employed for peeling fruits and vegetables, chocolate processing, and cleaning food processing equipment under strict hygiene standards.
Handling sodium hydroxide requires strict safety protocols due to its highly corrosive nature. Spanish manufacturers provide detailed safety data sheets (SDS) and training to ensure safe storage, handling, and transportation. Protective equipment such as gloves, goggles, and acid-resistant clothing is mandatory in industrial settings.
Environmental sustainability is a growing focus in Spain's chemical industry. Manufacturers are investing in cleaner production methods, waste minimization, and recycling initiatives. The chlor-alkali process is continuously optimized to reduce energy consumption and emissions, aligning with European Union environmental directives.
