The paper describes the synthesis and evaluation of a series of
environmentally friendly corrosion inhibitors. These products were designed and synthesized especially to introduce in North Sea oil fields. The two compounds selected, out of more than thirty compounds after
initial screening were subjected to a battery of tests (as corrosion inhibitors and as water- soluble low toxic chemicals). Finally, one chemical compound was selected with low toxicity, good corrosion protection, high biodegradability, and with low bioaccumulation. Keywords: environmentally friendly corrosion inhibitor, low toxicity, biodegradability, bioaccumulation, rotating cylinder electrode test.
