Sodium Petroleum Sulphonate

Formulations

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.
