  • Reaction of Sodium Azide with 1,1'–Dicyclohexenyl–Diepoxides 

    Darvich, Mohammad Raouf؛ Olyai, Abolfazl؛ Shabanikia, Akbar؛ Farkhani, Dariush (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2003-12-01)
    Nucleophilic ring opening of dl and meso 1,1¢- dicyclohexenyl diepoxides by sodium azide in dioxane and aqueous alcoholic medium give the corresponding azidoalcohols. The obtention of departure diepoxides from ...

  • Shape Selective Alkylation of Biphenyl with 1-octene on ((Al+C3H7Cl)+C2H4) Catalysts 

    Veli (Veliyeva), Sevil (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2003-12-01)
    Alkylation of biphenyl with 1-octene was investigated using ((Al+C3H7Cl)+C2H4) catalysts. The catalytic activity of ((Al+C3H7Cl)+C2H4) for the alkylation was studied at different temperatures, mol ratios of biphenyl ...

  • Potentiometric Study of Complex Formation Between Some Transition Metal Ions and 2 - Aminopyridine. Part 1. A Model for Therapeutic Agent for Wilson’s Disease 

    Joshaghani, Mohammad؛ Sotodehnejad, Masoud (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2003-12-01)
    The complexation reactions of some transition metal ions and 2-aminopyridine (2-ampy) were studied potentiometrically in aqueous solution at µ=0.1 M and 25 °C. The overall stability constants log β's of all species are ...

  • Synthesis of N, N΄3, 4-Dialkylamino-1, 2, 5-Oxadiazoles 

    Kakanejadifardi, Ali؛ Delfani, Farshad؛ Ranjbar, Bijan (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2003-12-01)
    N, N΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of N, N΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ...

  • A Comprehensive Empirical Correlation for prediction of Supersolubility and Width of the Metastable Zone in Crystallization 

    Naser, Iraj؛ Manteghian, Mehrdad؛ Bastani, Dariush؛ Mohammadzadeh, Mohsen (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2003-12-01)
    Prediction of supersolubility and the width of the metastable zone has been a major concern among the workers in the field of industrial crystallization. Operation of crystallizers under the optimum supersaturation low ...

  • Extension of Linear Isotherm Regularity to Long Chain Alkanes 

    Parsafar, Gholamabbas؛ Kalantar, Zahra (Iranian Institute of Research and Development in Chemical Industries (IRDCI)-ACECR, 2003-12-01)
    In this work, we consider each normal alkane as a hypothetical mixtureof methyland methylene groups, in which the interaction potential of each pair is assumed to be the average effective pair potential. Then, the LIR ...
