He, Jiahong published the artcileInsight into the corrosion inhibition property of Artocarpus heterophyllus Lam leaves extract, Computed Properties of 56317-21-6, the publication is Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) (2021), 260-270, database is CAplus.
In this work, the method (water extraction way) was uesd to acquire Artocarpus heterophyllus Lam leaves extract (AHLLE). We refer to the relevant references on the composition of Artocarpus heterophyllus Lam leaves and perform Fourier IR spectroscopy anal. for AHLLE. It can be concluded that AHLLE contains 2-(2,4-dihydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one (DPD), (2R,3R)-2-(2,4-dihydroxyphenyl)-3 ,5,7-trihydroxychroman-4-one (DPT), 3-(4-hydroxyphenyl)acrylic acid (HPT), and 5-(6-hydroxybenzofuran-2-yl)benzene-1,3-diol (HBB). Quantum chem. calculations (QCC) data and mol. dynamics (MD) simulations results show that DPD, DPT, HPT, and HBB all have the potential of excellent corrosion inhibitors. Scanning electron microscope (SEM) results and at. force microscope (AFM) test results show that after adding AHLLE to H2SO4 environment, the copper surface is still correspondingly flat. In addition, the results of electrochem. experiments indicate that the AHLLE is 500 ppm, the anti-corrosion efficiency obtained from electrochem. impedance spectroscopy data can reach 97.3%. With the temperature augments to 313 K, the corrosion inhibition nature of AHLLE can still be maintained to 97%. AHLLE is adsorbed onto the Cu surface and belongs to Langmuir monolayer adsorption.
