Oleyl Hydroxyethyl Imidazoline (CAS 27136-73-8) is an oil-soluble imidazoline corrosion inhibitor base, made from oleic acid and aminoethylethanolamine (AEEA). It is supplied as a brown viscous paste and is used as the film-forming base for oilfield and refinery corrosion-inhibitor formulations, and as an intermediate for water-soluble imidazoline derivatives.

FAQ
What is oleyl hydroxyethyl imidazoline used for? Mainly as the oil-soluble, film-forming base for corrosion-inhibitor formulations used in oil and gas production and refining, and as an intermediate for water-soluble imidazoline derivatives.
What is the specification? A brown viscous paste with density 0.90-1.00 g/cm3 at 25 °C, active content 98% min, flash point above 61 °C and pour point below 15 °C.
Is it oil-soluble or water-soluble? The free base is oil-soluble. To make a water-soluble corrosion inhibitor, it is normally derivatised (for example quaternised) downstream.
