Complexes containing five 4,5-disubstituted-3-mercapto-1,2,4-triazoles and Zn(II), Hg(II) and Cu(I) were synthesized and characterized by standard procedures (elemental analysis; IR, electronic and NMR spectroscopy, conductimetry and TG analysis). Both the thione as well as the thiolate forms of the ligands were evidenced to interact with the metal ions in the prepared complexes. The original m...
There is very little information in the literature concerning the production of mercaptans by microorganisms. Mercaptan production has been reported for anaerobes (Rettger, J. Biol. Chem. 2:71, 1906), fungi [Challenger, Sci. Progr. (London) 35:396, 1947], Escherichia coli (Fromageot and Moubacher, Enzymologia 2:121, 1937), and Proteus vulgaris (Masatashi, Biochem. Z. 136:198, 1923). However, Ma...
Natural gas is odorized by trace amount of mercaptans and organic sulfides to be recognized by individuals, in case of gas leakage. These materials may pollute the environment particularly in injection station at local gas plants. Therefore, removal of sulfur compounds from the remaining odorant in barrels is essential. To remove the residual portion of mercaptans and alkylsulfide mixtures diff...
