BARIUM DINONYLNAPHTHALENE SULFONATE

Description

Barium Dinonylnaphthalene Sulfonate is a brown or dark brown thick liquid, prepared from nonylene and naphthalene.It provides the lubricant with good antirust and demulsifying performance, and oil solubility as well. No deposit would be produced in preparation of additive packages.

Barium Dinonylnaphthalene Sulfonate is an excellent antirust and demulsifying agent. It can serve as antirust additive and emulsion breaker for antiwear hydraulic oils; antirust agent for industrial lubricating agent (such as paper machine oil, rock drill oil, steam turbine oil and circulation oil) running in damp environment;and antirust agent for lubricating grease as well.

Reference Dosage

The dosage is from 1.0% to 5.0%.

Anti-rust Additive BARIUM DINONYLNAPHTHALENE SULFONATE is used in lubricating oils to prevent rust and corrosion on metal surfaces. It forms a protective film on the surface of the metal, preventing moisture and other corrosive elements from coming into contact with the metal. This additive is commonly used in automotive, industrial, and marine applications where metal parts are exposed to harsh environments.

It is a highly effective anti-rust additive that provides long-lasting protection against corrosion. It works by forming a barrier between the metal surface and the surrounding environment, preventing moisture and other corrosive substances from reaching the metal. This helps to extend the lifespan of the metal parts and ensures smooth operation of machinery and equipment.

 BARIUM DINONYLNAPHTHALENE SULFONATE is compatible with a wide range of lubricating oils and can be easily mixed into various formulations. It is typically added in small concentrations to achieve the desired level of rust protection.

In addition to its anti-rust properties, BARIUM DINONYLNAPHTHALENE SULFONATE also offers other benefits such as improved lubricity and anti-wear properties. It can reduce friction and wear on metal surfaces, resulting in improved efficiency and longer equipment life.

Overall,  BARIUM DINONYLNAPHTHALENE SULFONATE is an essential additive in lubricating oils, providing effective rust protection and enhancing the performance and durability of metal parts.

Barium dinonylnaphthalene sulfonate is a type of sulfonate surfactant that is often used as an additive in lubricating oils and greases. This compound is part of the family of metal sulfonates and is known for its detergency and dispersant properties. Let’s break down the key components and functions of barium dinonylnaphthalene sulfonate:

### Key Components:

1. **Barium Salt:**
– Barium dinonylnaphthalene sulfonate is a salt of barium, where barium ions are combined with the sulfonic acid groups present in the dinonylnaphthalene structure.

2. **Dinonylnaphthalene Structure:**
– The hydrophobic (water-repelling) portion of the molecule is derived from dinonylnaphthalene, which is a hydrocarbon with a naphthalene ring. This hydrophobic tail provides compatibility with non-polar substances.

3. **Sulfonic Acid Groups:**
– The sulfonic acid groups in the molecule contribute to its hydrophilic (water-attracting) properties. These groups make it effective in interacting with water-soluble components.

### Functions and Applications:

1. **Detergency:**
– Barium dinonylnaphthalene sulfonate acts as a detergent, helping to keep engine components and machinery clean by preventing the formation of deposits, sludge, and varnish.

2. **Dispersancy:**
– The dispersant properties of this additive assist in keeping solid particles finely dispersed in the lubricating oil. This prevents the agglomeration of particles and promotes a cleaner system.

3. **Corrosion Inhibition:**
– It may provide corrosion protection by forming a protective film on metal surfaces, safeguarding against rust and corrosion.

4. **Neutralization of Acids:**
– This additive can neutralize acidic by-products formed during the combustion process, helping to control the acidity of the oil and mitigate corrosive effects.

5. **Oxidative Stability:**
– Barium dinonylnaphthalene sulfonate may contribute to the oxidative stability of lubricating oils, resisting the formation of oxidation by-products that can degrade the oil over time.

### Applications:

1. **Engine Oils:**
– Barium dinonylnaphthalene sulfonate is commonly used in engine oils, where its detergent, dispersant, and corrosion inhibition properties help maintain a clean engine and protect against wear.

2. **Industrial Oils:**
– It finds application in various industrial lubricants, including hydraulic fluids, gear oils, and metalworking fluids, where detergency, dispersancy, and corrosion protection are essential.

3. **Marine Lubricants:**
– The additive is used in marine lubricants to provide detergency, dispersancy, and protection against deposits in marine engines and systems.

4. **Specialized Lubricants:**
– Barium dinonylnaphthalene sulfonate may be included in specialized lubricants where high detergency and dispersancy are required for specific applications.

It’s important to note that the use of barium-based additives, including barium dinonylnaphthalene sulfonate, has faced environmental concerns due to the toxicity of barium. As a result, there has been a shift towards alternative additives with lower environmental impact. Users should refer to the manufacturer’s recommendations and specifications for optimal usage and be aware of regulatory considerations.
