Description

Sulfonic Acids, Petroleum are a complex mixture of alkylated aromatic sulfonic acids derived from petroleum feedstocks. These versatile organic acids are valued for their strong acidity and surfactant properties, making them critical intermediates and additives in numerous industrial processes. Key industries that utilize this product include lubricant manufacturing, metalworking, and the production of specialty chemicals and detergents.

Application

• Primary raw material for the synthesis of petroleum sulfonate salts, widely used as emulsifiers, demulsifiers, and corrosion inhibitors.
• Key intermediate in the production of lubricant and grease additives, enhancing detergency and rust prevention.
• Acid catalyst in various organic synthesis and alkylation reactions within the chemical manufacturing sector.
• Used in the formulation of metalworking fluids and industrial cleaning compounds.
• Precursor for anionic surfactants employed in enhanced oil recovery (EOR) applications.
• Component in the manufacture of specialty chemicals, including dyes and pesticide intermediates.

Quality Control

Our Sulfonic Acids, Petroleum are produced and tested under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as acid number, sulfonation efficiency, and viscosity are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its strong acid/organic solvent nature, ensure containers are made of corrosion-resistant materials (e.g., stainless steel, specific plastics). Recommended storage temperature is 15-25°C.
