Abstract

Preparation of 2, 6-Di-t-butyl-4-isopropylphenol (Ia).-. 4 solution of 60 g.(0.44 mole) of p- isopropylphenol in 50 inl. of benzene was alkylated with isobutylene at 50-60" using 2 ml. of concd. sulfuric acid as the catalyst. 8 After rl. weight gain of 60-65 g.(1.07-1.15 moles) of isobutylene the solution was washed once with water, once with 10% sodium hydroxide and three times with Claisen solution (a 50% potassium hydroxide solution diluted with an ...
