Alkylation of 2-chlorophenol with isobutylene. The catalyst was prepared in the autoclave by heating 644 g. (5 moles) of 2-chlorophenol with 4.5 g. (V, formula wt.) of aluminum turnings. Alkylation with isobutylene was effected at 80-90°and the product worked up to give 550 g. (60%) of 2terí-butyl-6-chlorophenol (b.p. 123°at 30 mm.; n1 2D°1.5265).Anal. Caled, for Ci0Hi3C1O: Cl, 19.2. Found: Cl, 19.3. Proof of structure of 2-tert-butyl-6-chlorophenol. A portion of the product of the above experiment was chlorinated with sulfuryl chloride to yield 2,4-dichloro-6-ier<-butylphenol (for chlorination method see under structure proof of 2,6diisopropylphenol). The 2,4-dichloro-6-
