What is Dinonylnaphthalenesulfonic Acid Used For

Dinonylnaphthalenesulfonic Acid CAS 25322-17-2, DNNSA for short, is a kind of important organic Acid compounds, with strong acidity and surface activity, its USES widely distributed in many fields of industrial production.

Catalyst field

Esterification reaction catalyst Dinonylnaphthalenesulfonic acid solution in the coatings, plastics industries such as esterification, Dinonylnaphthalenesulfonic acid can be used as efficient catalysts, promote the reaction of carboxylic acids and alcohols, Ester compounds (such as plasticizers, coating resins, etc.) are generated, and the reaction conditions are mild with high catalytic efficiency.

Polymerization catalyst: Dinonylnaphthalenesulfonic acid used in the polymerization of some polymer materials, such as olefin polymerization, synthetic resin, such as, can control the reaction rate and product structure.

Surfactants and emulsifiers

Dinonylnaphthalenesulfonic acid using its surface activity, can be used as emulsifier used in lubricating oil, cutting fluid and other industrial products, help the oil-water mixture to form stable emulsion, lubrication, dispersion properties of the promotion product.

Dinonylnaphthalenesulfonic acid in printing ink, dye and other fields, can improve the dispersivity of the system, prevent particles together, improve product stability.

Metal processing and treatment

Metal cleaner: By virtue of its acidity and surface activity, it is used for cleaning metal surfaces, removing impurities such as oil stains and rust, and is especially suitable for the pretreatment of precision parts.

Electroplating additives: Dinonylnaphthalenesulfonic acid in electroplating process, can adjust the ph value of solution and dispersion, uniformity and adhesion of the coating.

Petrochemical industry

Dinonylnaphthalenesulfonic acid as oilfield chemicals and can be used for crude oil demulsification and drop stick in the process of mining, enhance oil recovery; It can also be used in petroleum refining to assist in removing impurities and improving the quality of oil products.

Other industrial uses

Dinonylnaphthalenesulfonic acid in coatings, adhesives and other products, can be used as dispersant or stabilizers, improve the uniformity and storage stability of the system.

In some cases, it can be used as an acidic catalyst to replace traditional inorganic acids, reducing equipment corrosion and environmental pollution.

It is important to note that dinonylnaphthalenesulfonic acid solution has certain corrosion resistance and irritating, need to follow the safety practices in the process of use and storage, avoid direct contact with the skin or mucous membrane. Its specific application needs to be adjusted according to industry demands and process conditions. We are a professional manufacturer of wholesale dinonylnaphthalene sulfonic acid.
