HCID 121601-Ethyl-4-MethylbenzeneYield 27.9%

Procedure

The same reactor used in Example 4 was charged with a feedstock containing a (3.6 wt.%, 10.4 mol %) concentration of ethylene in toluene. At a reaction temperature of 100° C., 5.95 g (9.0 mL) of a catalyst analyzed to contain 19.71 wt.% fluorine gave 49.4% ortho-, 22.7% meta-, and 27.9% para-ethyl-methyl-benzene with 44.4 mol % conversion, compared to 17.1 mol % conversion for a control catalyst in which the polymer had not been fluorinated.
