Procedure

This example illustrates a reaction system comprising a single reactor for forming styrenated p-cresol. Example 9 was run in a manner similar to Example 8, with the exception that a single reactor was used for the 70° C. reaction and the 90° C. finishing reaction and clay addition were used. The styrene feed was fed over time periods ranging from 2.5 to 4 hours. The amount of triflic acid used ranged from 1.7 to 2.6 g. The molar ratio of styrene to p-cresol was maintained at 1.95. The composition of the resulting styrenated p-cresol composition, based on total GC area, was as follows:
