摘要

本文以丁香酚、多聚甲醛和正丁胺为原料合成了一种新的丁香酚基苯并恶嗪单体。通过1H NMR、13C NMR、紫外-可见光谱和FT-IR光谱对合成的单体进行了表征。然后将该单体与异氰酸酯硬化剂在三种不同组成的低碳钢表面共聚合。然后在马弗炉中固化得到聚苯并恶嗪-氨基甲酸乙酯。用紫外光谱和红外光谱对共聚物进行了表征。利用极化和EIS技术研究了共聚物对3.5% NaCl溶液的防腐性能。为了进一步支持这项工作，还对单体及其共聚物进行了DFT研究。为了进一步证明单体和共聚物的疏水性，还进行了吸水和凝胶吸附实验。

Study of Corrosion Resistant Property of Benzoxazine Synthesised from Euginol with N-Butylamine and Copolymerised with Polyurethane on Mild Steel

In this work, we have synthesized a new eugenol based benzoxazine monomer from eugenol, paraformaldehyde and n-butyl amine. The synthesized monomer was characterized by 1H NMR, 13C NMR, UV-Visible and FT-IR spectroscopy. The monomer was then co-polymerized with isocyanate hardener on the surface of the mild steel with three different composition. After that it was cured in a muffle furnace to get poly(benzoxazine-urethane). The copolymer’s characterized by UV and FT-IR spectroscopic techniques. The anti-corrosive property of the co-polymer was investigated using polarization and EIS techniques against 3.5% NaCl solution. For additional support for this work, DFT studies also carried out for monomer and its copolymer. Water absorption and gel absorption studies were also done to add evidences for the hydrophobicity of the monomer and the copolymers.

期刊介绍： Oriental Journal of Chemistry was started in 1985 with the aim to promote chemistry research. The journal consists of articles which are rigorously peer-reviewed. The journal was indexed in Emerging Science citation index in 2016. The Editorial board member consists of eminent international scientist in all fields of Chemistry. Details of each member and their contact information is mentioned in website. The journal has thorough ethics policies and uses plagiarism detection software(ithenticate) to screen each submission. The journal has recently partnered with publons as a part of making our reviews more transparent. The journal has recently incorporated PlumX for article level matrix. The journal is promoting research on all social and academic platforms mentioned in PlumX guidelines. The journal uses google maps to improve on the geographical distribution of Editorial board members as well as authors.
