Efficiency of Non-Ionic Surfactants Based On Oleic Acid as Corrosion Inhibitors for Carbon Steel Pipelines in Deep Oil Formation Water Saturated with CO2 at 40

摘要

ABSTRACT Preparation of nonionic surfactants from Oleic acid and their application in the field of corrosion inhibitors are the main goal of the present work. In this respect, oleic acid reacted with maleic anhydride using Diles Alder reaction to produce adduct, which esterified with ethoxthylated aniline to produce branched nonionic surfactants. The effect of ethylene oxide modification on both surface activity and corrosion inhibition efficiency on carbon steel pipelines in deep oil wells' fo.
