Sodium Petroleum Sulphonate Sodium Petroleum Sulphonate

what is sps?

SPS: stands for Sodium Petroleum Sulphonate.

Sodium petroleum sulfonates: sps are unique materials due to their dual function as surfactants and Anti-corrosion. The polar nature of the end of the sulfonate molecule acts as a typical anionic surfactant and orients itself with water or other polar materials while the hydrocarbon tail bridges the nonpolar phase.

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.

Sodium petroleum sulfonates features and benefits:

Sodium petroleum sulfonates (SPS) can be widely used as the primary emulsifier in the formulation of lubricating compounds.

 Sodium petroleum sulfonate is used in the following cases:

1. Fluid cutting 
2. Metalworking lubricants
3. Detergency
4. rust inhibitive
5. automotive rust proofing

Applications of SPS or Sodium Petroleum Sulfonate:

1. Metalworking Fluids
2. Anti-Corrosion Compounds
3. 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.
4. Ore Flotation
5. Demulsifiers
6. Motor Oil and Fuel Additives
7. Overbasing
