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.
Suggested
SPS: GL 1649L, GL 1649M
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.

Demulsifiers
GL
1649H 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.

SPS: GL 1649H
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.
