ABSTRACT:
A method for removing high molecular weight solid and liquid tars and oligomers from halogenated Lewis acids catalysts is disclosed. The Lewis acids incorporating such tars and oligomers are treated with an oxidizing agent such as chlorine, a halogen fluoride or mixtures thereof for a time and at a temperature sufficient to oxidize said solid tars and oligomers. The oxidation causes such tars and oligomers to form oxidation products, which can be separated from the halogenated Lewis acid.
