✦ Synopsis

Recent publications 1,2,3) on the alkylation of benzene and toluene by the WC16-C2H5A1C12 system prompt us to report our observations stressing the difference between the behaviour of this metathesis catalyst and that of a simple Lewis acid such as C2H5A1C12 for the alkylation of benzene.

C2H5AlC1, alone is indeed an effective alkylating reagent 4'5) (A), but it gives a mixture of mono-, di-and higher alkylated products, while the

It is shown that the system TiC14-(C2Hs)2AICI-(C6Hs)2Mg is highly efficient and very promising as a catalyst of the filling of polyethylene during the polymerization with inorganic fillers (chalk, marble powder, perlite, kaolin and dolomite). The preliminary activation of the filler, the formation t
