Abstract
Halogenated alkyl substituted phenols may be dealkylated by treating a compound such as 5-t-butyl-2-fluorophenol with a diealkylation catalyst such as an acid acting compound at dealkylation conditions whereby the t-butyl substituent is removed and the resulting compound comprising 2-fluorophenol is recovered.
