Claim Text:
1. A process for preparing a second mixture selectively enriched in aromatic-hydroxyl group containing compounds from a first mixture comprising hydroxyl group containing compounds, where the hydroxyl group containing compounds include one or more functional groups selected from aromatic-hydroxyl groups and aliphatic-hydroxyl groups, the method comprising the steps of (a) contacting the first mixture with a polymeric reagent comprising a polymer having one or more functional groups of formula (CH the functional group is capable of reacting with the hydroxyl group containing compounds when the first mixture containing the hydroxyl group containing compounds contacts the reagent; n is 1 to 4; R X is selected from the group consisting of Cl, Br, and OS(O) wherein one or more of the functional groups of the polymeric reagent forms a covalent bond with the hydroxyl group of one or more of the hydroxyl group containing compounds; (b) washing the polymer resulting from step (a) with a solvent selected from the group consisting of optionally branched C (c) contacting the polymer resulting from step (b) with a mixture comprising 1,1,3,3-tetramethylguanidine (TMG) and R
