    Ghavami, Raoof؛ Abdollahi, Hamid؛ Saleem Khan, Mohammad (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1997-06-01)
    The complexation reactions between methylthymol blue (MTB) and Co2+, Ni2+, Cu2+, Zn2+ and Pb2+ ions have been studied in different water-methanol mixtures at pH ...

  • Selective Mono Bromination of 1,4-Dihydropyridines 

    Rastgar Mirzaei, Yousef؛ Moshtaghi Zenouz, Adeleh (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1997-06-01)
    2-monobromomethyl 1,4-dihydropyridines is selectively synthesized by bromination of the parent compound by 1.1 equivalents of pyridinium bromide perbromide in dichloromethane/pyridine at -20 °C. The same reagent in ...

  • Synthesis of 2-Mono and 2,6-Disubstituted Methyl-1,4-Dihydropyridines 

    Rastgar Mirzaei, Yousef؛ Akbari Dilmaghani, Karim (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1997-06-01)
    The 2-mono and 2,6-disubstituted methyl-1,4-dihydropyridines were synthesized by reaction of morpholine, thiophenol, 8-hydroxyquinoline, 2-naphthol and 2-mercopto-1-methyl imidazole with the 2-mono bromo and ...

  • Synthesis and Characterization of Aminocarboxylato Iridium(III) Complexes 

    Kooti, Mohammad؛ Merola, Joseph S. (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1997-06-01)
    Aminocarboxylic acids, such as 2-aminobenzoic acid, react easily with [Ir(COD)(PMe3)3]Cl, (COD=1,5-cyclooctadiene), in THF to produce hydridoaminocarboxylato iridium(III) complexes in high yields. ...

  • The Effect of Superficial Feed Velocity on the Column Flotation Recovery in Comparison with the Conventional Flotation Cells 

    Rahimi, Rahbar؛ Tahmooresi, Majid (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1997-06-01)
    Flotation is the most important process for concentrating mineral ores. This process may occur in any vessel such as column flotation, which has been used widely during the last decade and the conventional flotation ...
