Reaction Steps
To a one liter round-bottomed flask equipped with a stirrer, thermometer, and addition funnel was charged 151.3 grams (1.4 moles) of p-cresol. The mixture was heated to 70° C., followed by the addition of 5 μL of trifluoromethane sulfonic acid via a 100 μL syringe. Under a nitrogen blanket, 284.5 grams (2.73 moles) of styrene was placed into the funnel and then added dropwise, with stirring, over a period of three hours. During styrene addition, the pot temperature did not exceed 80° C. Stirring was continued at a pot temperature of 70° C. for a period of 1.5 hours after all the styrene had been added. The resultant styrenated p-cresol composition analyzed as follows:
