Highly crosslinked macroreticular styrene-divinylbenzene copolymer matrix for superior mechanical and thermal stability.
Sulfonic acid functional groups providing strong acidity and high ion exchange capacity (≥ 4.7 meq/mL in H⁺ form).
Optimized particle size distribution (0.3–1.2 mm) for low pressure drop and excellent flow dynamics in fixed-bed reactors.
Exceptional resistance to organic fouling and thermal degradation up to 120 °C in continuous service.
Regenerable with dilute mineral acids, enabling long service life and cost-effective process cycles.
Esterification and transesterification reactions, including biodiesel production (FAME synthesis).
Hydration of olefins to produce fuel-grade alcohols (e.g., tert-butanol from isobutylene).
Hydrolysis of esters, nitriles, and acetals in fine chemical and pharmaceutical intermediate synthesis.
Alkylation reactions requiring strong Brønsted acidity under mild conditions.
Removal of trace acidic impurities in solvent purification and monomer refining streams.
