摘要
以4-羟基香豆素、丙二腈和4-硝基苯甲醛为原料合成了新型缓蚀剂2-氨基-4-(4-硝基苯基)-3-氰基- 4,5 -二氢吡喃(3,2-c)香豆素(AND),并在1 M HCl介质中对低碳钢(MS)进行了失重法和表面技术扫描/电子/显微镜(SEM)鉴定。通过光谱(FT-IR,1HNMR和13CNMR)对AND作为缓蚀剂进行了表征。失重实验表明,通过提高缓蚀剂的浓度,可以提高缓蚀剂的缓蚀性能。为了支持我们的结果,采用扫描电镜对1.0 M HCl介质中有and和没有and的质谱表面进行了澄清。在AND的最大利用浓度下,抑菌率为96%
New green organic molecules as corrosion inhibitor namely, 2-amino-4-(4-nitrophenyl)-3-cyano-4, 5-dihydropyrano (3,2-c) coumarin (AND) was synthesized starting from 4-hydroxycoumarin, malonitraile and 4-nitrobenzaldehyde and tested on mild steel (MS) in 1 M HCl media by a weight loss method and identification of the surface technique employee scanning/electron/microscope (SEM) studies. The AND as an inhibitor compound have been elucidate spectroscopically (FT-IR ,1HNMR and 13CNMR) The weight loss investigation demonstrated that inhibition performances have been improved via concentration raising of inhibitor. To support our results scanning electron microscopy was employed to clarify the surface of the MS with and without AND in 1.0 M HCl media. The inhibition performance rate was 96% at the maximum utilized concentration of AND
