摘要

Syntheses are reported for secondary and tertiary amines as well as ammonium salts containing cycloacetal fragments. The inhibitory activity of these compounds for St3 steel in 3% aqueous sodium chloride was determined relative to reagents Neftekhim NS and Neftekhim 1M commonly used in the oil and natural gas industry. The greatest protection was found for the tertiary amine, N‑(1,3‑dioxan‑4‑ylmethyl)‑N‑hexylprop‑2‑ene‑1‑amine (82%), which is only slight less than the corresponding indices of the reference inhibitors (94-98%), indicating that a further search among this class of compounds might yield new effective reagents.
