105 g of phenol and 5.3 g of aluminum oxide catalyst that was calcined in air at a temperature of 450° C. was charged in an autoclave and heated to 150° C. A raffinate stream containing 80% isobutylene, 18.7% isobutane and 1.4% 1-butene was then charged over a period of 3.5 hours. The amount of raffinate charged was 75 g with a isobutylene to phenol mole ratio of 0.95:1. The yield of OTBP at the end of 7 hours was 49%. The amount of 1-butene in the feed that reacted to form 2-sec-butylphenol was 1.3%.
