Product Details
Barium Petroleum Sulfonate (T701/T701A)
High-Performance Corrosion Inhibitor & Rust Preventative Additive
CAS Number: 61790-48-5
Product Code: T701 (Petroleum Base) / T701A (Synthetic Base)
Grade: Industrial Lubricant Grade
Product Overview
At Chemost, we specialize in supplying high-performance lubricant additive components to blending plants and wholesalers worldwide. Our Barium Petroleum Sulfonate (T701) is a neutral sulfonate rust preventative designed for the most demanding industrial applications.
Also known in the industry as a Corrosion Inhibitor, this additive is the backbone of modern rust preventive formulations. It exhibits excellent oil solubility and adheres strongly to metal surfaces, creating a protective barrier against moisture, salt spray, and acidic atmospheres.
Whether you require standard Petroleum Barium Sulfonate (T701) or Synthetic Barium Sulfonate (T701A), Chemost ensures consistent quality compliant with international standards.
Chemical Properties & Structure
Chemical Name: Sulfonic acids, petroleum, barium salts
CAS Registry Number: 61790-48-5 (Petroleum Base)
Appearance: Brown, viscous liquid
Solubility: Soluble in petroleum oils and common organic solvents; insoluble in water.
Note: While chemically similar, T701 is derived from natural petroleum fractions, whereas T701A is produced synthetically. T701 generally offers superior oil solubility, while T701A may offer higher purity and consistency.
Key Features & Benefits
- Superior Salt Spray Resistance: Acts as a robust shield, significantly extending the life of metal parts in marine and humid environments.
- Excellent Demulsibility: Separates readily from water, ensuring the oil film remains intact.
- Acid Neutralization: Effectively neutralizes acidic by-products formed during oxidation.
- Non-Staining: Safe for use on ferrous and non-ferrous metals (excluding silver).
- Film Consistency: Forms a uniform, oily film that does not crack or peel.
Technical Specifications
Standard typical values for T701. For specific batch data, please refer to the COA.

Applications
Barium Petroleum Sulfonate is a versatile additive primarily used in the manufacturing of:
Rust Preventive Oils: The primary additive for solvent-diluted, lubricating, and sealing rust preventive oils.
Hydraulic Fluids: Used as a corrosion inhibitor in petroleum-based hydraulic systems.
Industrial Greases: Adds anti-rust properties to lithium and calcium-based greases.
Metalworking Fluids: Provides inter-process rust protection for machined parts.
Formulation Guidance & Synergy
Recommended Dosage
- Anti-rust oils: 3.0% – 15.0%
- Greases: 1.0% – 3.0%
- Lubricating oils: 0.5% – 2.0%
Synergistic Performance (The "Power Combo")
For applications requiring extreme humidity cabinet and salt spray protection, Barium Petroleum Sulfonate is rarely used alone.
Expert Tip: We recommend compounding Barium Petroleum Sulfonate (T701) with Barium Dinonylnaphthalene Sulfonate (BDNNS).
Why? T701 provides a thick, reservoir-like protection layer, while BDNNS offers exceptional film-forming capabilities and water displacement. Together, they create a synergistic effect that significantly outperforms either component used individually.

Frequently Asked Questions (FAQ)
Q: What is the difference between T701 and T701A?
A: T701 is based on natural petroleum sulfonates, which typically offers better cost-performance and solubility in varied base oils. T701A is synthetic, offering higher purity and specific molecular weight control for specialized formulations.
Q: Can you provide samples for lab testing?
A: Yes, we provide samples to lubricant manufacturers and additives wholesalers for compatibility testing. Please contact our sales team.
Q: What is the packaging?
A: Standard industrial packaging includes 200kg Iron Drums or IBC Tanks.
Q: Does this product contain solvents?
A: T701 is usually supplied in a diluent oil. It does not contain volatile solvents unless requested in a pre-diluted custom blend.
