    Omidkhah, Mohammad Reza؛ Seyyed Shabestari, Seyyed Ahmad (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1994-12-01)
    Methyl tertiary butyl ether (MTBE) is known as a promising substitute for tetra ethyl lead (TEL) in order to increase the octane number of gasoline. MTBE process, as many other processes, has two distinguished section, ...

  • Extraction-Fluorimetric Determination of Low Levels of Copper by 1,7- Diaza-15-Crown-5 and Rose Bengal 

    Shamsipur, Mojtaba؛ Fathi, Mohammad Reza (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1994-12-01)
    A simple and sensitive extraction-fluorimetric method for the determination of copper is reported. The 1,7-diaza-15-crown-5-copper-rose Bengal (DA15C5-Cu-RB) ternary complex is quantitatively extracted into chloroform, ...

  • Manganese and Cobalt Salts of Para-Amino-Benzoic Acid Supported on Silica Gel as Oxidizing Catalysts 

    Hashemi, Mohammad M.؛ Chazanfari, Dadkhoda (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 1994-12-01)
    Para-Aminobenzoic acid is supported on silica gel via reaction of activated silica gel and p-aminobenzoic acid which is then converted to its manganese and cobalt salts. A mixture of the manganese and cobalt salts of ...
