Naphthalene sulfonates are derivatives of sulfonic acid which contain a Naphthalene functional unit.
A related family of compounds are the aminonaphthalenesulfonic acids.
Of commercial importance are the alkyl Naphthalene sulfonates, which are used as superplasticizers in concrete.
They are produced on a large scale by condensation of naphthalenesulfonate or alkylnaphthalenesulfonates with formaldehyde.
Examples include:
amaranth dye
amido black
armstrong's acid
congo red
Evans blue
suramin
trypan blue
Naphthalene sulfonates can be used in a variety of applications.

Naphthalene sulfanate maintains its dispersibility over a wide pH range, pH: 2-12.
Usage areas
Naphthalene Sulfonate does not cause foaming and can be used with anionic or nonionic surfactants.
Dispersant of disperse dyes: By adding 10-50% by weight Naphthalene sulfanate, the wettability, grinding and migration properties of the powder dispersion are improved and a secondary fluctuation is prevented.
Auxiliary dyeing agents: By adding 0,1-2% by weight of Naphthalene sulfanate to the dyestuff, excellent migration and leveling properties of the dyestuff are obtained.
Pigment dispersants: When making aqueous and emulsion paints, 0.5-3% by weight Naphthalene sulfanate is added to the pigments to obtain excellent wetting and permeability.

Naphthalene Sulfonate can be found in the content of fertilizers to prevent caking.
Naphthalene Sulfonate is used as a dispersing and leveling agent for dyestuffs.
Naphthalene Sulfonate improves the dyeing quality by ensuring that the dye pigmentation is well absorbed.
When Naphthalene sulfonate is added in the range of -50, a disperse dye dispersant, an improvement is observed in the dispersion, wettability and grinding properties of the dyestuff.
Pigment and fillers must be dispersed in water with SNS before being added to other suspensions and emulsions.
The process of decreasing fluidity and dispersion in paint is possible in cement.
Naphthalene Sulfonate provides fluidity in the concrete and allows the concrete to be dispersed smoothly without gaps.
Thus, the strength of concrete increases and its segregation is prevented.
Naphthalene Sulfonate is also used in fluid mortars prepared for repair.
Naphthalene Sulfonate is a precipitator for cationic materials and a coating stabilizer for basic paints.
