Neutral barium dinonylnaphthalene sulfonate (T705A) is an excellent rust inhibitor and demulsifier. Because its chemical structure is different from that of basic barium dinonylnaphthalene sulfonate (T705), its base value is smaller than that of basic barium dinonylnaphthalene sulfonate T705, and it can neutralize some acidic additives in oil products. It is also small, and T705A will not produce precipitation when preparing a compounding agent.
Neutral barium dinonylnaphthalene sulfonate contains lipophilic non-polar groups and hydrophilic polar groups. Since most of the metal surfaces are charged, the hydrophilic groups will be adsorbed by various physical and chemical effects. on metal surfaces. During adsorption, the hydrophilic group is directed towards the metal and the lipophilic group is positioned away from the metal. Since this product is adsorbed on the surface of Chemicalbook metal, on the one hand, the properties of the interface are changed, the energy state of the metal surface tends to be stable, and the corrosion rate is slowed down; on the other hand, the lipophilic group of this product forms a layer of hydrophobicity on the metal surface. The protective film prevents the movement of charges and substances associated with the corrosion reaction, reducing the reaction rate.
