Description

Sulfuric Acid CAS NO 14279-86-8 is a fundamental and highly versatile inorganic acid essential for a vast array of industrial chemical processes. Its powerful acidic and dehydrating properties make it a critical reagent for synthesis, pH adjustment, and catalysis. This product is indispensable for manufacturers and R&D facilities in sectors including chemical manufacturing, water treatment, metal processing, and laboratory analysis.

Application

• Chemical Synthesis: Acts as a catalyst and dehydrating agent in the production of fertilizers (e.g., phosphoric acid, ammonium sulfate), explosives, dyes, and other organic compounds.
• Metal Processing & Pickling: Used for cleaning and removing oxide scale from the surface of ferrous metals (iron, steel) before galvanizing or other treatments.
• Water & Wastewater Treatment: Employed for pH adjustment and neutralization in industrial effluent treatment plants and municipal water systems.
• Petroleum Refining: Serves as a catalyst in alkylation processes to produce high-octane gasoline components.
• Laboratory & Analytical Reagent: Used as a standard titrant and a key component in various analytical methods and sample digestion procedures.
• Electrolyte Production: A primary component in lead-acid batteries (automotive, industrial) as the electrolyte solution.
• Pulp & Paper Industry: Utilized in the digestion process for breaking down lignin in wood chips during paper production.

Quality Control

Our Sulfuric Acid is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, concentration, and impurity profiles. We provide Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, heavy metal content, and residue on ignition. Our quality commitment supports compliance with relevant industrial and reagent-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, organic compounds, and metals. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture and dilution. Secondary containment is recommended. Store at controlled room temperature.
