Highly selective catalytic activity for esterification and transesterification reactions under mild conditions.
Thermally stable up to 150 °C, enabling robust performance in continuous fixed-bed reactor systems.
Sulfonic acid functional groups grafted onto a macroporous polystyrene-divinylbenzene matrix ensure low leaching and long service life.
Low pressure drop and excellent hydraulic stability due to uniform spherical bead morphology (0.3–1.2 mm particle size).
Regenerable with dilute acid washes, supporting sustainable operation and reduced chemical consumption.
Biodiesel production via catalytic transesterification of vegetable oils and waste cooking oil.
Ester synthesis in fine chemical manufacturing, including flavor & fragrance esters and pharmaceutical intermediates.
Continuous-flow dehydration reactions such as acetic acid + ethanol → ethyl acetate + water.
Removal of trace metal ions and acidic impurities in specialty solvent purification streams.
Catalytic upgrading of pyrolysis oil by esterification of free fatty acids to improve stability and heating value.
