Description

Dinonylnaphthalenesulfonic Acid is a high-molecular-weight organic sulfonic acid valued for its strong acidity and excellent solubility in non-polar organic media. This compound serves as a highly effective acid catalyst, surfactant, and ion-exchange agent in demanding industrial processes. It is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking a stable, oil-soluble acid source.

Application

• Acid Catalyst in organic synthesis and polymerization reactions, particularly where solubility in hydrocarbon phases is required.
• Demulsifier Component in the petroleum industry for breaking crude oil emulsions.
• Lubricant & Fuel Additive as a detergent and dispersant to control deposits and corrosion.
• Cation Exchange Agent in non-aqueous systems and for the preparation of metallic soaps.
• Surfactant Intermediate for the synthesis of specialized anionic surfactants with oil-soluble properties.
• Coating & Ink Additive to improve pigment wetting, dispersion, and adhesion properties.
• Metal Extraction & Processing aid in hydrometallurgical applications.
