The catalytic action of sulfonic acid resins is described by assuming two different kinds of active sites located on the pore surface and within the polymer.
The isomerization of 1-butene is studied as model reaction.
New thermally stable acid resins are developed and used in the hydration of 1-butene. The polymeric catalysts are obtained by fluorination/chlorination of ion exchange resins or alternatively by acylation and sulfonation of crosslinked polystyrene beads.
