EFFECT OF THE SURFACE AREA OF PLATINUM ON THE ACTIVITY OF A BIFUNCTIONAL ALUMINOPLATINUM CATALYST IN THE SYNTHESIS OF ALKYLIMIDAZOLES FROM DIAMINES AND CARBONYL ACIDS

Article abstract of DOI:10.1007/BF00863569

An investigation has been conducted into the effect of the acid and dehydrogenating functions of an aluminoplatinum catalyst on the synthesis of 2-methylimidazole from ethylenediamine and acetic acid.It has been established that formation of the intermediate 2-methylimidazoline involves the acid Al2O3 centers and its rate of formation is greater than the rate of its subsequent dehydrogenation to 2-methylimidazole on the Pt centers.The symbatic nature of the variations in the 2-methylimidazole yield and the surface area of the platinum in the aluminoplatinum catalyst has been demonstrated.Keywords: C-alkylimidazoles, 2-methylimidazole, aluminoplatinum catalyst.
