実験手順

Naphthalene (800 g) and the catalyst from example 2 (40 g or 5% by weight on the naphthalene) are contacted with propylene at a temperature of 250° C. with an added pressure of propylene of 0.8×105Pa for 1 hour 30 minutes in a 2 liter Parr pressure autoclave operated under agitation. Analysis of the reaction mixture by gas chromatography gives a conversion of 82.3%, a yield in the 2,6-diisopropyl naphthalene of 15.0% and a yield in 2,7-diisopropyl naphthalene of 9.4%. The sum of the diisopropyl naphthalene represents 32.5% of the conversion. The selectivity to the 2,6-diisopropyl naphthalene is 18.2% and the selectivity to the 2,7-diisopropyl naphthalene is 11.5%.
