Series of coordination complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) metal with 4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol, as a ligand has been successfully prepared in alcoholic medium. The prepared complexes were characterized quantitatively and qualitatively by using: microelemental analysis, FTIR spectroscopy, UV-visible spectroscopy, (1)H(More)
In this article the effects of using maltenes, which have been pre-separated recently from paraffinic base asphalt to modify asphalt pavement in variety of percentages has been investigated. Further modification has been performed by applying chlorine gas using ultra violet and ferric chloride as catalyst at certain temperature in order to increase the(More)
BACKGROUND Schiff's bases are excellent ligands which are synthesized from the condensation of primary amines with carbonyl groups. FINDINGS The classical reaction for the synthesis of Schiff's bases in an ethanolic solution and glacial acetic acid as a catalyst was followed in the synthesis of substituted sulfamethoxazole compounds. CONCLUSIONS Some(More)
