Description

Dodecylbenzenesulphonic Acid, Compound With Ethylenediamine (2:1) is a high-purity, neutralized salt form of dodecylbenzenesulfonic acid (DBSA) offering enhanced handling stability. This compound is valued for its dual functionality, combining the surfactant properties of the sulfonic acid with the neutralizing and complexing characteristics of ethylenediamine. It serves as a critical intermediate and performance additive in the production of industrial lubricants, corrosion inhibitors, and specialized emulsifiers. Manufacturers in the chemical synthesis, metalworking, and petroleum industries rely on this material for consistent quality and reliable performance in demanding formulations.

Application

• Lubricant and Grease Additive: Acts as a multifunctional component providing detergency, anti-wear, and corrosion inhibition properties in metalworking fluids and industrial lubricants.
• Corrosion Inhibitor Intermediate: Used in the synthesis of high-performance corrosion inhibitors for oilfield chemicals, cooling water systems, and fuel additives.
• Emulsifier and Dispersant: Functions as an effective emulsifier in pesticide formulations, textile processing aids, and pigment dispersions.
• Chemical Synthesis: Serves as a key intermediate or catalyst in organic synthesis reactions, particularly where a stabilized sulfonic acid source is required.
• Petroleum Industry Additive: Employed in fuel and crude oil treatment formulations for its demulsifying and sludge-dispersing capabilities.
• Industrial Cleaning: A component in specialized industrial and institutional (I&I) cleaning formulations requiring acidic cleaning with controlled reactivity.

Quality Control

Our production of Dodecylbenzenesulphonic Acid, Compound With Ethylenediamine (2:1) adheres to a stringent quality management system. Every batch is tested against established in-house specifications to ensure consistent purity, composition, and performance. Key parameters including assay, moisture content, and amine value are verified. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent compound, it should be stored separately from strong bases, oxidizing agents, and reactive metals. Ensure containers are kept upright to prevent leakage.
