SODIUM SULFONATE

Sodium Sulfonate is recommended for use in soluble oils and semi-synthetic fluids to impart all of the benefits of natural sodium sulfonate. Sodium sulfonates are made from natural petroleum oil feedstocks. Ataman’s sodium sulfonates provide excellent emulsion quality and corrosion resistance. Sodium sulfonates have a long history of use in metalworking fluids. They function as emulsifiers and corrosion inhibitors.

 

 

As a result, the distribution of molecular weights of our products is very broad, while the distribution of molecular weights of typical synthetic sodium sulfonates is narrow. 
The broad distribution of molecular weights of Ataman sodium sulfonates enhances the ability of the sulfonates to interact with the oil and provides excellent emulsification compared to a synthetic sodium sulfonate of the same molecular weight. 
Ataman’s sodium sulfonates possess a structure which is composed of a poly-alkylated aromatic ring system, where the alkylates are primarily branched and short-chained. 
The typical synthetic sodium sulfonates are mono-alkylated aromatic ring systems where the alkylates are linear and long-chained. 
The presence of these short-chained and branched alkyl aromatic groups in Sonneborn sodium sulfonates improves their compatibility with the base oil. 
The resulting benefits are enhanced emulsion and rust prevention characteristics.

Applications
Ataman’s sodium sulfonates provide excellent emulsion quality and corrosion resistance. 
The low molecular weight sulfonates provide excellent emulsion performance, while the high molecular weight sulfonates provide an unsurpassed rust preventive coating. 
Depending on the application, the balance of these two properties is critical for performance in any market. 

In the oilfield, drilling and mining markets, which are less concerned with rust prevention, the strong emulsifier Sodium Sulfonate grade is preferred. 
In the industrial oils market, where rust prevention is a large concern, sodium sulfonate is used in rust preventive oil. 

In the metalworking industry, a balance of both the emulsion and corrosion performances is critical to a successful formulation. 
Here the market prefers the balanced emulsion and corrosion resistance of Sodium Sulfonate.


Sodium Sulfonate is recommended for use in soluble oils and semi-synthetic fluids to impart all of the benefits of natural sodium sulfonate. 


Possibly the most common rust preventive chemistry is the various forms of sulfonate. 

And there is significant variety: natural or synthetic sulfonates, neutral or overbased, benzene or naphthalene, and delivered as sodium, magnesium, calcium or barium salts.

Even with the same base number and metal, the source of the sulfonate itself can cause variation in activity. 

Synthetic sulfonates from different manufacturers could have different chain lengths, aromatic group (benzene or naphthalene), alkyl chain substitution, branching or chain length distributions. 
Natural sulfonates could have been produced as by-products of the petroleum refining process, or white oil production.


The main attraction of sulfonates is their multiple modes of action. 
Sulfonates can be overbased to deliver a large alkalinity reserve in the form of metal carbonates, which react with acids in solution. 
Additionally, the sulfonate and the counter-ion can both bind to the metal (oxide) surface.

The effectiveness of a sulfonate as a rust preventive can depend on the counterion. 
Of the commonly available sulfonates, barium sulfonates are often more effective than calcium salts, which are often more effective than magnesium or sodium sulfonates. 
However, as water-soluble barium compounds are poisonous, their use is undesirable in some countries, though not yet banned.


Sulfonates are used as additives for metal working fluids and engine oils. 
They provide special functions such as surfactant and rust-prevention functions.

APPLICATIONS

Metalworking Fluids

Sodium sulfonates have had a long history of use in metalworking fluids. It function as emulsifiers and corrosion inhibitors.
In liquid system, sulfonates can hold oil and water apart so that they can co-exist & form an emulsion.

Anti-Corrosion Compounds

High molecular weight sodium sulfonates adhere to metal surfaces and provide excellent moisture barriers. 
It can be compounded with petroleum oils, waxes, petrolatums and various synthetic materials. 
Finished products are used in applications such as preservative oils and automotive rust proofing formulations. 
They are also compatible with a wide range of solvents when thin films are desirable.
On solid surface, sulfonates functions like adhesive, holding oil to metal. 
By chemically bonding oil to metal, sulfonates prevent water and air from reaching the surface of the metal.


Ore Flotation

Ore Flotation sulfonates have been used as flotation agents for various metals and minerals. 
The ability of the sulfonates to wet the surface of particles renders the ore hydrophobic. 
This allows the ore to adhere to air bubbles and move to the surface in the froth.
In ore flotation, sulfonates bind the ore particles to air bubbles, in a froth, allowing them to rise and separate from rock.


Demulsifiers

Demulsifiers grade sulfonates can act as de-emulsifier. 
A Bulky structure prevents them from forming a continuous protective film around a droplet. 
This allows two droplets to contact one another, forming a large droplet which separates from solutions.


Motor Oil and Fuel Additives
The sodium sulfonates are often converted to calcium or barium salts for this application; however, in some situations the sodium sulfonates may be preferred. 
Detergency and rust inhibitive properties are the most important functions of Motor Oil and Fuel Additives when used as additives.


Overbasing
Overbasing is a process of beefing up a solfonate molecule with extra atoms like calcium and magnesium so that it will seek out and neutralize excess acids in a mixture. 
This process is typically used in motor oil additives.

This process is typically used in motor oil additives.


These neutralized first-intent, water and oil soluble synthetic sodium sulfonates are used in dispersant, emulsification, metal working, corrosion prevention, lube oil additive, agriculture, ore floatation, enhanced oil recovery, and industrial cleaning applications.


SULFONATES: Natural sulfonates originated as a by-product in the refining of petroleum and are sulfonated extracts from lubricating oil fractions. 
Synthetic sulfonates are sulfonated alkyl and dialkyl derivatives of benzene, xylene or naphthalene and are offered as an alternative for the natural sulfonates.

Sulfonates provide excellent emulsification and corrosion resistance properties.
The various types of sulfonates are characterised by different molecular weight, the particular salt and the alkalinity. 
The low equivalent weight sulfonates provide strong emulsion performance while the high molecular weight sulfonates provide the basis for exceptional rust preventative coatings.
Depending on application, the balance of these two properties is important;

• For metalworking fluids, a balance of both emulsification and corrosion performance is key to a successful formulation
• In industrial oils where corrosion, protection is important and high molecular weight sulfonates are preferred
• For greases, the ability to readily convert to a gel is important along with its corrosion resistance and extreme pressure EP performance
• In oilfield and mining, where corrosion prevention is less important, strong emulsification is preferred

THE APPLICATION OF ATAMAN KIMYA’s full range of Sulfonates comprises low cost, extremely stable and reliable products providing emulsification and rust prevention. 
Its  Barium, Calcium and Sodium Sulfonates are suitable for use in a variety of fields and applications, including;

• Lubricant oil additives
