Corrosion study of iron using piperazine derivatives as inhibitors
The corrosion of iron by HC1 using cyclic polyethyleneimines as inhibitors has been done many times. Piperidine, a cyclic six membered ring CH.NH has attracted the most attention as an inhibitor because of the high basicity ...
Palladium catalysed oligomerization of 1-alkynes
The oligomerization of 1-pentyne using palladium acetyl acetonate catalyst with various solvents and ligands was investigated. An equimolar mixture of HOAc and Et N proved to be a superior solvent. The major product observed ...
An electronic spectral study of some Fe(II) magnetic isomers in solution and a spectral-structural correlation with their Ni(II) analogs
Pseudooctahedral Fe(II) Complexes of the hexadentate ligand, tris4-[(6-R)-2-pyridyl]-3-aza-3-butenylamine, where R is either H or CH^ (Figure 1) , have been studied in solution by electronic spectroscopy. The complexes ...
