Highly selective clay-based catalyst optimized for condensation and esterification reactions.
Thermally stable up to 250 °C, enabling robust performance in continuous industrial processes.
Low heavy metal content, supporting compliance with stringent food-contact and pharmaceutical-grade requirements.
Consistent particle size distribution ensures uniform bed packing and predictable pressure drop in fixed-bed reactors.
Pre-activated and ready-to-use — eliminates need for on-site calcination or activation pretreatment.
Production of plasticizers (e.g., dioctyl phthalate, DOA) via esterification of phthalic anhydride or adipic acid.
Synthesis of bio-based lubricants and synthetic esters from renewable feedstocks.
Catalytic dehydration in fine chemical intermediates, including acetal and ketal formation.
Refining of natural oils and fatty acid derivatives for high-purity oleochemical applications.
Downstream processing in pharmaceutical API synthesis requiring mild, heterogeneous acid catalysis.
