27Al NMR MAS study of AlEt3 − nClnMgCl2 systems

Abstract The 27 Al NMR MAS spectra of surface species of aluminum-containing compounds AlEt 3 − n Cl n ( n = 0–3) on MgCl 2 have been measured. The data obtained indicate that 5- and 6-coordinated aluminum compounds form on the MgCl 2 surface. The majority of the AlCl 3 supported in small amounts on MgCl 2 was found to be 4-coordinated.
