A solution of naphthalene (16.3 g, 0.127 mole) in 25 ml of heptane was heated to 80° C. in the presence of 3 g of the catalyst. 1-decene, 14.9 g (0.106 mole), was added quickly. The reaction was stirred at 80° C. for 8 hours. The catalyst was removed by filtration and the excess naphthalene removed by rotary evaporation. The product was fractionated to give 11.5 g (40% yield) of decylnaphthalene, and 12.4 g (57.3% yield) of didecylnaphthalene. The didecylnaphthalene has KV: 9.9 cS@100° C.; 97 cS@40° C.; VI 87.
