Product Details
Synthetic Barium Sulfonate
High-Performance Corrosion Inhibitor & Rust Preventative
Product Category: Lubricant Additive Component
Chemical Family: Synthetic Sulfonates
Common Code: T701A / Synthetic T701
Product Overview
Chemost acts as a specialized manufacturing partner and supplier for the lubricant industry. Our Synthetic Barium Sulfonate is a neutral, high-molecular-weight sulfonate designed specifically for formulating premium rust preventive oils and industrial greases.
Unlike natural petroleum sulfonates, this synthetic variant is derived from alkylbenzene feedstocks, offering higher purity, consistent molecular weight distribution, and lighter color. It functions as a powerful Corrosion Inhibitor, adsorbing onto metal surfaces to form a protective film that effectively isolates moisture and aggressive ions (such as chlorides).
This additive is essential for blending plants requiring a reliable rust preventative with excellent demulsibility and salt spray resistance.
Chemical Properties & Structure
Chemical Name: Barium salt of synthetic sulfonic acid (Alkyl Benzene Sulfonate)
General Formula: $(R-SO_3)_2Ba$
CAS Number: 61790-48-5 (General Category) or specific to alkyl chain length.
Molecular Structure: Contains a polar sulfonate head (attaches to metal) and a non-polar alkyl tail (solubilizes in oil).
Key Chemical Characteristics:
- Neutrality: Typically neutral to slightly basic.
- Structure: Micellar structure in oil, capable of solubilizing small amounts of water.
- Thermal Stability: Stable at standard processing temperatures for lubricants.
Technical Specifications
Typical physical properties. Batch-specific data is provided in the COA.
Property | Test Method | Typical Value |
|---|---|---|
Appearance | Visual | Brown Viscous Liquid |
Sulfonate Barium Content | ASTM D3712 | ≥ 50% |
Water Content | ASTM D95 | ≤ 0.3% |
Kinematic Viscosity (100°C) | ASTM D445 | 30 – 100 mm²/s |
Flash Point (COC) | ASTM D92 | > 180°C |
Key Performance Features
Superior Salt Spray Resistance: The barium molecule provides exceptional resistance to salt fog and humidity, making it the preferred choice for marine and export shipping protection.
Excellent Demulsibility: Unlike calcium or sodium sulfonates, Synthetic Barium Sulfonate separates rapidly from water, preventing emulsion formation in hydraulic and circulating oils.
Non-Staining: Safe for use on yellow metals (copper, brass) and aluminum, as well as ferrous metals.
Film Consistency: Forms a continuous, thin oily film that does not crystallize or peel over time.
Applications & Usage Guidance
Synthetic Barium Sulfonate is a versatile component compatible with mineral oils (Group I, II) and synthetic hydrocarbons (PAO).
Primary Applications
- Rust Preventive Oils: Used as the primary anti-rust agent in solvent-diluted and oil-based rust preventives (dewatering fluids).
- Industrial Greases: Incorporated into lithium, calcium, or aluminum complex greases to enhance rust protection without degrading the grease structure.
- Hydraulic & Circulating Oils: Added at low treat rates to prevent corrosion in systems prone to water ingress.
Recommended Treat Rates
Application | Recommended Dosage (wt%) |
|---|---|
Rust Preventive Oils (Long-term) | 5.0% – 15.0% |
Rust Preventive Oils (Inter-process) | 2.0% – 5.0% |
Lubricating Greases | 0.5% – 3.0% |
Hydraulic Fluids | 0.1% – 0.5% |
Formulation Compatibility
Synthetic Barium Sulfonate is designed for blending flexibility.
Solubility: Soluble in most paraffinic and naphthenic mineral oils.
Synergy: It shows excellent synergistic effects when combined with:
Oxidized Petrolatum: To improve film thickness and salt spray hours.
Zinc Dialkyldithiophosphates (ZDDP): Compatible in hydraulic formulations.
Sorbitan Esters (Span-80): To enhance humidity cabinet performance.
Quality Control & Documentation
We understand that validation is critical for B2B procurement. Chemost provides a complete documentation package for every order:
- TDS (Technical Data Sheet): Comprehensive performance data.
- MSDS (Material Safety Data Sheet): GHS compliant safety handling.
- COA (Certificate of Analysis): Provided with every shipment for quality assurance.

Frequently Asked Questions (FAQ)
Q: How does Synthetic Barium Sulfonate differ from Petroleum Barium Sulfonate?
A: Synthetic Barium Sulfonate is produced from synthetic alkylbenzene, resulting in a product with higher purity and consistency between batches. It generally has a lighter color and better compatibility with synthetic base oils compared to petroleum-derived sulfonates.
Q: Is this product suitable for dewatering fluids?
A: Yes. Due to its non-emulsifying nature and water displacement properties, it is an excellent choice for dewatering rust preventives.
Q: What is the packaging for bulk orders?
A: We supply in 200kg steel drums or 1000kg IBC tanks. Bulk ISO tank shipments are available for large-scale manufacturers.
Q: Can I use this in food-grade lubricants?
A: Generally, Barium compounds have toxicity concerns and are not recommended for H1 food-grade lubricants. Please consult us for Calcium Sulfonate alternatives for food-grade applications.
