Sodium Petroleum Sulphonate

Introduction
GL 1649 Sodium petroleum sulfonates are unique materials because of their dual function as surfactants and rust inhibitors. The polar nature of the sulfonate end of the molecule functions as a typical anionic surfactant, orienting itself with water or other polar materials while the hydrocarbon tail provides the bridge to the nonpolar phase.

Formulations
GL 1649 may be used at concentrations of 10% to 22% by weight in selected industrial and metalworking applications.

Applications

Metalworking Fluids
Sodium sulfonates have had a long history of use in metalworking fluids. GL 1649 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. GL 1649H 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. GL 1649H 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
GL 1649 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.

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 GL 1649H 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.
