3. Features & Benefits
-
Unmatched Acid & Dehydrating Power: The capacity for sulfonation, nitration, and dehydration makes it indispensable for thousands of chemical reactions.
-
Exceptional Purity (Battery Grade): Free from metal impurities that cause self-discharge and corrosion of lead plates.
-
Thermal Stability: The ability to be used in high-temperature processes without rapid decomposition.
-
Competitive Base Price: One of the most economical chemicals, given its immense volume of global production.
4. Industrial Applications
-
Agriculture & Fertilizer: The primary material for producing phosphoric acid from phosphate rock, and subsequently DAP/MAP fertilizers.
-
Petroleum Refining: An alkylation catalyst and a refining agent for kerosene and lubricating oils.
-
Battery Manufacturing: The main electrolyte in automotive lead-acid and UPS batteries.
-
Metal Extraction: Leaching of copper, uranium, and nickel ores.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance is severely corrosive and a strong oxidizer. Its dilution with water is intensely exothermic and dangerous (always add acid to water). Its SOx vapors are toxic. The Arnico MSDS is of vital importance.
-
Storage Conditions: Store in carbon steel or 316 stainless steel tanks, sealed, in a dry, cool environment, and away from organic materials, alkalis, and active metals (zinc, aluminum). An earthing system is mandatory.
-
Personal Protective Equipment (PPE): Full PVC acid-resistant clothing, long gloves, boots, a face shield, and chemical goggles are required.
6. Quality Assurance & COA
Arnico Sulfuric Acid shipments are provided with a Certificate of Analysis (COA) detailing the concentration and a heavy metal analysis.
