Abstract: At present, a majority of corrosion inhibitors applying in oilfield mainly consist of organic amine compounds. In order to understand and control the organic amine content of corrosion inhibitors and give full play to corrosion inhibitors effect, it is very important to determine accurately the organic amine content of corrosion inhibitors. In this paper, the amine value of three organic corrosion inhibitors with hydrochloric and ethanol method, high chlorine acid non-aqueous titration method by different acid-base indicators and solvents were contrastively analyzed. The experimental results show that titration end-point change is acute, accurate, and fast with appropriate addition amount of corrosion inhibitor.
