摘要

Benzyl alcohol has been used to prepare a single phase MgCl _2.6BzOH molecular adduct as a support for an ethylene polymerization catalyst (Ziegler catalyst). The structural, spectroscopic and morphological aspects of the MgCl_2.6BzOH molecular adduct and the Ziegler catalyst have been thoroughly studied by various physicochemical characterization techniques. The presence of MgO_6 octahedrons due to the interaction of Mg~(2+) with six -OH groups of the benzyl alcohol is confirmed from a Raman feature at 703 cm~(-1), and structural studies. The supported catalyst activity has been evaluated for the ethylene polymerization reaction. The lower polymerization activity of the titanated Ziegler-Natta catalyst compared with a standard catalyst is attributed to the strong interaction of titanium chloride with the support and associated electronic factors.
