Method for removing tert-butyl groups from tert-butyl phenol compounds

By bringing a p-butylphenol compound or m-butylphenol compound in the gas phase into contact with a solid acid catalyst, i.e., a silica-alumina catalyst or alumina catalyst while heating, butyl groups are removed from the butylphenol compound and at the same time, highly purified isobutylene is reco...
