Highly selective Brønsted acid catalyst optimized for esterification and transesterification reactions.
Thermally stable up to 200 °C, enabling robust performance in elevated-temperature batch and continuous processes.
Low volatility and non-corrosive to standard stainless-steel reactor equipment.
Water-tolerant formulation maintains catalytic activity in systems with trace moisture.
Easy handling as a free-flowing solid—no special containment or fuming concerns during storage or dosing.
Biodiesel production via transesterification of vegetable oils and animal fats.
Synthesis of plasticizers such as dioctyl phthalate (DOP) and diisononyl phthalate (DINP).
Catalysis in polyester resin manufacturing, including unsaturated polyesters for composites.
Ester-based lubricant additive synthesis, including trimellitates and adipates.
Production of fragrance esters and pharmaceutical intermediates requiring mild, controllable acidity.
