摘要

苯酚（或邻烯丙基苯酚）与多聚甲醛和取代苯胺（或烯丙胺）反应生成3-烯丙基-、3-芳基-或8-烯丙基-3-芳基-1,3-苯并恶嗪。对合成的化合物的缓蚀活性进行了研究，结果表明，8-烯丙基同源物在15%盐酸溶液中的保护度(Z)达到96-98%。在苯并恶嗪核心的C8碳原子上缺少烯丙基取代基导致保护系数下降到75-76%。

Synthesis of Substituted 1,3-Benzoxazines and Their Anticorrosion Activity

The reactions of phenol (or ortho-allylphenol) with paraformaldehyde and substituted anilines (or allylamine) yielded 3-allyl-, 3-aryl- or 8-allyl-3-aryl-1,3-benzoxazines. A study of the corrosion inhibitory activity of the synthesized compounds revealed that the degree of protection (Z) in the case of 8-allyl homologues in a 15% HCl solution reaches 96–98%. The absence of an allyl substituent at the C⁸ carbon atom of the benzoxazine core leads to a decrease in protection to 75–76%.

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
