摘要：

The Al-27 NMR MAS spectra of surface species of aluminum-containing compounds AlEt3-nCln (n = 0-3) on MgCl2 have been measured. The data obtained indicate that 5- and 6-coordinated aluminum compounds form on the MgCl2 surface. The majority of the AlCl3 supported in small amounts on MgCl3 was found to be 4-coordinated.
