N-benzylidene-2-aminobenzimidazol (BA) has been investigated as corrosion inhibitor for mild steel in corrosive solution utilizing weight loss technique complemented with Scanning electron microscopy (SEM).The weight loss method results clarified that BA has good inhibiting impact for mild steel corrosion in corrosive solution, with efficiency of 7...

The present invention relates to a coating composition for inhibiting corrosion on metal surface comprising an 2-Amino-5-mercapto-1,3,4-thiadiazole, benzene-1,4dialdehyde and a polar solvent that is able to reduce corrosion rate on metals .

Eco-friendly corrosion inhibitor derived from coumarin namely3-acetamidocoumarin was synthesized by reaction of salicylaldehyde and aceturic acid. The chemical structure of 3-acetamidocoumarin had been elucidation some spectroscopic techniques (Fourier transform infrared (FT-IR) and proton Nuclear magnetic resonance (NMR)) and elemental micro analy...

Stabilization standards of PVC films are fundamentally depend on essential laws: solvation and "reverberation" Stabilization. The photo-stabilization of poly(vinyl chloride) (PVC) films by epoxidized oleic acid was investigated. Photo-stabilization activities were determined by monitoring the carbonyl, polyene and hydroxyl indices with irradiation...

The acid corrosive consumption hindrance process by Cherry Sticks extraction as a green corrosion inhibitor had been explored by utilizing the weight loss method. Impact of temperatures on the consumption conduct in the existence of the inhibitor at a concentration of 50*10-2 g/L was examined at the temperatures of 30, 40, 50 and 60 °C. The results...

Calix[4]pyrrole and modified calix[4]pyrrole derivatives have been synthesized and characterized, namely calix [4] pyrrole [meso-octamethyl-calix [4] pyrrole], 1, meso-tetramethyl-tetrakis-(4-hydroxyphenyl) calix[4] pyrrole, 2, meso-tetramethyl-tetrakis-(3-hydroxyphenyl) calix[4] pyrrole, 3, mesotetramethyl-tetrakis-[(4-N, N-diethylacetamide) pheno...

Calix [4] pyrrole derivative was used to target lanthanide cations. Meso tetramethyl-tetrakis-[(4-N, N-diethylacetamide) phenoxymethyl] calix [4] pyrrole, L2 was synthesised. This receptor constituted of hard donor atoms at the lower rim which interact with lanthanide cations being hard cations. 1H NMR investigations showed that both, the pyrrolic...

Novel calix[4]arene derivative containing mixed pendant arms in its lower rim, 25, 27-bis (diethylamino) ethoxy-26, 28-(bis-methoxyethoxy) calix[4]arene, L3, has been synthesized to target the heavy metal cations. 1 H NMR investigations seems to indicate that the receptor L3 interacts preferentially with Hg 2+ , Cd 2+ , Pb 2+ and Ag + in acetonitri...

A series of new Cu(II), Pt(II), VO(II), Fe(II), and Co(II) complexes (1--5) with 3-methyl-6,7-diphenyllumazine are described. Similarly, complexes from 2-thiouracil with Cu(II) (6,7) and Pt(II) (8) have been prepared and characterized by spectroscopic methods. All the complexes were assayed for their anti-HIV-1 and HIV-2 activity by examination of...
