HR-SEM and FT-IR dataset for green corrosion inhibition activity of 4-{[4-(pyridin-2-yl)piperazin-1-yl]methyl}aniline at CO2 atmosphere

Mild steel (MS) corrosion inhibiting aptitude of 4-{[4-(pyridin-2-yl)piperazin-1-yl]methyl}aniline (PPMA), is presented [1], [2], [3] in this data set. Explorations of synthesized PPMA are carried out by FT-IR spectral analysis, nuclear magnetic resonance (NMR) and high resolution scanning electron microscopy (HR-SEM). The inhibition activity is investigated by potentio-dynamic method. The FT-IR and NMR results revealed that structure. These data sets are ideal tool for the applications like physical and chemical-engineering field.

Chemical Science Specific subject area Physical chemistry and Chemical engineering Type of data Table, Figure and Schemes. How data was acquired Spectroscopic and microscopic data used to the (corrosion resistive) engineering applications is explored. Data format Raw data. Parameters for data collection NMR and FT-IR spectra were recorded, FT-IR spectra were recorded with thermo scientific spectrometer, model no. iS5 equipped with attenuated total reflectance (ATR) competence which is implemented by Zn-Se crystal detector. Each spectrum was recorded with an achievement time of 18 s. The FT-IR dimension was scanned at a range from 40 0 0 to 400 cm −1 . Description of data collection FT-IR and NMR spectral consequence reveals that structure and purity of the catalyst such as PPMA [4] . HR-SEM morphology of as-synthesized PPMA and MS interacted PPMA is predicted. Data source location Department of Chemistry, Laxminarayana College of Arts & Science, Dharmapuri, Tamilnadu, India, and SAIF-IIT Madras.

Value of the Data
• The data were represent a valuable collection of the intact individual spectroscopic and microscopic data of PPMA interacted MS. • The microscopic images and plots provide a novel way to look at the effectiveness of the corrosion inhibition potential of PPMA and further evolutions for other researchers to expand the future outcomes [2][3][4][5] . • The FT-IR data provides specifying binding frequencies of the PPMA with MS [6] .
• This data allows other researchers to explore or extend the corrosion inhibition activity analysis of petroleum oil storage containers at different atmosphere.

Data Description
We present data includes the more information on (See Tables 1 and S1) the HR-SEM data of PPMA interaction with MS and Fig. 1 show the morphology of the reported materials. The Fig. 2 and Schemes S1 and 1 shows the synthetic scheme and corrosion inhibition efficiency data in (See Table 2 ). The resulted data are provided in Supplementary Table S1 . Scheme 1. Synthesis of PPMA.

Characterization techniques
The high resolution scanning electron microscopy (HR-SEM) was carried out on a FEI Quanta FEG 200 instrument facility at 25 °C. The taster was equipped by introduce a minute amount of primed material on a carbon coated copper network and allowing the solvent to evaporate. FT-IR spectra were recorded with thermo scientific spectrometer, model no. iS5 equipped with attenuated total reflectance (ATR) competence which is implemented by Zn-Se crystal detector. Each spectrum was recorded with an achievement time of 18 s. The FT-IR dimension was scanned at a range from 40 0 0 to 400 cm -1 .
Interpretation of FT-IR and NMR spectral data of PPMA is mainly focused on the MS interaction with PPMA vibrations at 408.0 cm −1 indicate that C-N-O bending, and 3150.4, 3270.0 cm −1 represent the NH and NH 2 stretching vibrations is confirmed by the PPMA adsorbed on the MS surfaces (see Supporting Information Table S1).
