Latest Patents

Yan’s patent, “Aqueous Formulation of Oil-Soluble Corrosion Inhibitor, and Preparation Method and Regeneration Method Thereof,” describes a method for producing a stable, water-based formulation of an oil-soluble corrosion inhibitor.

The process first identifies the temperature at which the formulation’s conductivity falls to no higher than 100 μS/cm. Water is then added gradually to a homogeneous mixture of the inhibitor and solvent oil to form a reverse micelle liquid, which is heated to that temperature. Separately, non-ionic and anionic surfactants are mixed with water and heated to the same temperature. The two mixtures are combined and stirred for no more than two minutes before being cooled immediately. The disclosure presents the resulting formulation as straightforward to produce and use, with high stability.
