They are typically produced by the alkylation of benzene/toluene with propylene to form cumene then O 2 is added with H 2SO 4 to form phenol (Hock process). In addition to the reactions above, many other more specialized reactions produce phenols: • rearrangement of esters in the Fries rearrangement
