MgCl2.6PhCH2OH – A new molecular adduct as support material for Ziegler–Natta catalyst: synthesis, characterization and catalytic activity

Abstract

Benzyl alcohol has been used to prepare a single phase MgCl2.6BzOH molecular adduct as a support for an ethylene polymerization catalyst (Ziegler catalyst). The structural, spectroscopic and morphological aspects of the MgCl2.6BzOH molecular adduct and the Ziegler catalyst have been thoroughly studied by various physicochemical characterization techniques. The presence of MgO6 octahedrons due to the interaction of Mg2+ 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.
