Highly selective acidic clay-based catalyst optimized for low-temperature condensation reactions.
Controlled acidity profile ensures consistent performance and minimizes side reactions such as polymerization or charring.
Thermally stable up to 200 °C, enabling reliable operation in continuous fixed-bed reactor systems.
Low dust generation and excellent mechanical strength reduce pressure drop and extend catalyst bed life.
Non-toxic, non-corrosive formulation supports safer handling and reduced environmental impact versus liquid acid alternatives.
Fine chemical synthesis — including Friedel-Crafts alkylation and acylation of aromatic compounds.
Production of fragrance intermediates, such as coumarin derivatives and alkylated benzenes.
Manufacturing of pharmaceutical precursors requiring mild, heterogeneous acid catalysis.
Dehydration and esterification reactions in specialty ester production (e.g., plasticizers and lubricant additives).
Upgrading bio-based feedstocks via selective dehydration of sugar derivatives and glycerol derivatives.
