The inhibitory effect of diethanolamine (DEA) on corrosion of mild steel in 0.5 M H 2 SO 4 was investigated by various corrosion monitoring techniques. Galvanostatic polarization study revealed that this compound is a very good inhibitor. The inhibition efficiency (I%) varies in the range of 88.7% to 55.3 % for a concentration range of 10 -3 M to 10 -7 M at 303 K, respectively. A study of corrosion potential (E corr ) reveals that DEA is a mixed type inhibitor. DEA inhibited mild steel corrosion due to physical adsorption of the inhibitor on the metal surface. The study at higher temperatures indicates that the inhibition efficiency decreases with the increase in temperature. The adsorption of DEA on the mild steel surface in 0.5 M H 2 SO 4 follows the Frumkin's adsorption isotherm. The results of potentiostatic polarization study revealed that DEA is a strong passivating additive. The results of infra red (IR) spectroscopy, scanning electron microscopy (SEM) and quantum chemical study supplement the results of the electrochemical techniques.

Facile Synthesis and Structural Characterization of Some Phthalazin-1(2H)-one Derivatives as Antimicrobial Nucleosides and Reactive Dye

A NEW series of 2,4-disubstituted phthalazin-1(2H)-one derivatives were synthesized via nucleophilic attach of N-2 of phthalazin-1(2H)-one derivatives on different monosuccharides. Synthesis of phthalazinone nucleosides were very effective as antimicrobial. Also the phthalazinone moiety can be used in synthesis of reactive nucleosides and dyes that were chemically bonded with proteins and fibers respectively as afforded highly stability of dyestuff wool and cotton textiles. The structure of the prepared compounds was elucidated by physical and spectral data like FT-IR, 1 H-and 13 C-NMR.

Gum exudates of Azadirachta indica (GAI) was tested as corrosion inhibitor for carbon steel in 1 N H2SO4 by means of different techniques viz., gravimetric experiments, electrochemical polarization and impedance studies, IR and SEM techniques. Nature of adsorption is reported and it follows Langmuir isotherm. Polarization method indicated mixed mode behaviour of the inhibitor. AC impedance studies supported mitigation effects of gum exudates of Azadirachta indica. IR and SEM studies reveal the protection of carbon steel through adsorption.
