Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Vengatesh, G., once mentioned the application of 41979-39-9, Name is Piperidin-4-one hydrochloride, molecular formula is C5H10ClNO, molecular weight is 135.592, MDL number is MFCD00041019, category is piperidines. Now introduce a scientific discovery about this category, Formula: C5H10ClNO.
Experimental and theoretical evaluation of new piperidine and oxaquinuclidine core containing derivatives as an efficient corrosion inhibitor for copper in nitric acid medium
The inhibition efficiency of copper corrosion in 1 M HNO(3)by five piperidine and oxaquinuclidine core containing compounds namely 2,4,6,11-tetraphenyl-9-oxa-1,5-diazatricyclo [5.3.1.0(3.8)] undecane (OX1), 2,4,6,11-tetraaryl (4-methoxyphenyl)-9-oxa-1,5-diazatricyclo [5.3.1.0(3.8)] undecane (OX2), 2,4,6,11-tetraaryl (4-chlorophenyl)-9-oxa-1,5-diazatricyclo [5.3.1.0(3.8)] undecane (OX3), 2,4,6,11-tetraaryl-p-tolyl-9-oxa-1,5-diazatricyclo [5.3.1.0(3.8)] undecane (OX4), and 2,4,6,11-tetraaryl (4-fluorophenyl)-9-oxa-1,5-diazatricyclo [5.3.1.0(3.8)] undecane (OX5) has been investigated using gravimetric method, electrochemical studies, FT-IR, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), DFT and Monte Carlo simulation techniques. Inhibitors are chosen based on electron donating and accepting ability to the metal surface. These compounds differentiated in phenyl ring containing electron withdrawing (Cl, F) and electron releasing (OCH3, CH3) substituents. Experimental and computational studies showed that methoxy (OCH3) substituent exhibit more efficiency compared to other compounds and it is due to more electron donating nature of the OCH(3)group. The adsorption of the inhibitors on copper surface obeyed Langmuir adsorption isotherm. Polarization results show that OXs are acting as a mixed type of inhibitors. In the surface characterization studies, change in frequency (FT-IR), change in surface roughness (SEM) and appearance of additional element peaks (EDX) before and after film formation confirmed the protective layer formation. Quantum chemical parameters and Monte Carlo simulation studies further evidenced by the inhibitor adsorption of the copper surface.
