  • Method of inhibiting corrosion using a corrosion inhibitor derived from vegetable oils
    Patent number: 10221368
    Abstract: The present invention is directed to a formulation of corrosion inhibitors for corrosion control of low carbon steel piping, carrying different fuels products, obtained in refineries or petrochemical processes. The composition comprises active imidazoline inhibitors derived from vegetable oil selected from the group consisting of sunflower, canola, soybean, safflower, corn and mixtures thereof that are reacted with a polyalkylated polyamines such as diethylenetriamines (DETA), triethylenetetramine (TETA) and tetraethylenepentamine (TEPA). The imidazoline is reacted with 1 to 3 moles of a carboxylic acid having 2 to 6 carbon atoms. The product obtained is formulated with 50 to 60% weight of an aromatic solvent and 10 to 20 wt % of an alcohol.
