| Abstract: | Dithiocarbamate DTC - 1 corrosion inhibitor was synthesized by reaction of urea with carbon disulfide. The product synthesized was characterized by IR spectrum and the result showed that the above mentioned compound was the target compound, and it was evaluated on stability, solubility , emulsification and corrosion inhibition. The result showed that the corrosion inhibitor DTC - 1 had good stability, solubility, and no tendency to emulsify. It had good compatibility and corrosion inhibition in saline water and it was suitable in weakly acidic, neutral and alkaline fluid, and it could be used in wide range of temperature. Therefore it had prospects to be widely used in oilfields. |
