Hydrotalcite before and after its calcination was characterized for surface area, crystalline phases and basicity. Both the hydrotalcite, particularly after its use in the benzylation reaction, and the catalyst derived from it by its calcination at 200-800 degrees C show high catalytic activity for the benzylation of toluene and other aromatic compounds. The catalytically active species present in the catalyst in its most active form are the chlorides and oxides of iron on the catalyst surface.</p>10aactivation by calcinations10abenzylation of aromatic compounds10abenzylation of toluene10aFe-Mg-hydrotalcite1 aChoudhary, Vasant, R.1 aJha, Rani1 aChoudhari, P., A.  uhttps://library.ncl.res.in/content/highly-active-and-reusable-catalyst-fe-mg-hydrotalcite-anionic-clay-friedel-crafts-type-0
