摘要： A process is described for the contemporaneous preparation of mesitylene and durene, characterized in that mesitylene and durene are obtained exclusively starting from pseudo-cumene without the use of any further chemical compound, operating in continuous, at a temperature ranging from 210 to 400null C., at a pressure ranging from 1 to 50 bar, with a weight space velocity ranging from 0.1 to 20 hoursnull1 and in the presence of a catalyst based on crystalline metal-silicates in acid form. After the recovery of mesitylene and durene from the reaction raw product, some of the remaining components of the raw product itself are recycled and fed to the reactor together with the pseudo-cumene.

摘要： The present invention regards a catalytic composition comprising gallium, at least one element chosen in the group of the lanthanides, and a zeolite belonging to the MFI, MEL or MFI/MEL families, the crystal lattice of which is made up of silicon oxide and at least one metal oxide chosen from among aluminium oxide, boron oxide and gallium oxide. Preferably, in the catalytic compositions of the present invention a zeolite is used belonging to the MFI family characterized by crystallites which for at least 90% have diameters smaller than 500 null and which can form agglomerates of submicron dimensions characterized by possessing at least 30% of the extrazeolitic porosity in the region of the mesopores. The catalytic compositions of the present invention can, in addition, contain rhenium. These catalytic compositions are useful in processes of aromatization of hydrocarbons containing from 3 to 6 carbon atoms, preferably, hydrocarbon mixtures containing olefins.
