Naphthalene (80 g) and the catalyst from example 1 (4 g or 5% by weight on the naphthalene) are contacted with propylene at a temperature of 220° C. with an added pressure of propylene of 0.8×105Pa for 3 hours in a 300 ml Parr pressure autoclave operated under agitation. Analysis of the reaction mixture by gas chromatography gives a conversion of 89.0%, a yield in the 2,6-diisopropyl naphthalene of 34.4% and a yield in 2,7-diisopropyl naphthalene of 11.8%. The sum of the diisopropyl naphthalene represents 51.7% of the conversion. The selectivity to the 2,6-diisopropyl naphthalene is 38.7% and the selectivity to the 2,7-diisopropyl naphthalene is 13.3%.
