CATALYSIS OVERVIEW
AMBERLYST™ polymer based catalysis involves mostly the use of functionalized styrene divinylbenzene copolymers with different surface properties and porosities. They are supplied as spherical polymers in the gel or macroreticular form. They have been used for 40 years in a variety of reactions.
Besides their catalytic performance, Amberlyst™ polymer catalysts are easy to handle and show a low degree of corrosivity. They are the catalysts of choice for some large markets such as fuel ethers, and bisphenol A. Alternatively these catalysts can be doped with various metals to enhance their catalytic properties. Today more and more neutral adsorbents with extended surface properties are used as carriers for biocatalysts and metal complexes.
AMBERLYST catalysts are available in a wide range of particle sizes (from 0.3 mm to 1.2 mm) which have been optimized for their end use to allow good selectivity, low pressure drop and lowest cost operations.
Our major building blocks for Amberlyst catalysts are polystyrene based copolymers but acrylic and phenolic backbones are also available. If you are looking for a specific polymer or functional group on a polymeric catalyst please feel free to contact us. We are interested in working with you.
