Claim Text:
1. A method for conducting an acid-promoted chemical reaction, the method comprising contacting an acid-reactive organic precursor in liquid form with a solid heterogeneous acid catalyst comprising a polyolefin structure of a macroscopic size of at least 1 micron in at least one dimension, wherein surfaces of the polyolefin structure have carboxylic acid groups and either sulfonic acid or phosphonic acid groups appended thereto, wherein the solid heterogeneous acid catalyst possesses an acid density of at least 6 mmol H + /g, and wherein said acid-promoted chemical reaction is selected from dehydration, esterification, etherification, aldol condensation, enolization, oxidation, dehydrogenation, acetalization, and alkene hydration reactions, and wherein said solid heterogeneous acid catalyst is re-used in a subsequent acid-promoted chemical reaction.
