FBD300 Catalyst Resin


FBD300 is a superior macroporous strong-acid catalyst resin which has been developed from poly(vinylbenzenesulfonate) cation exchangers. While ordinary commercial styrene-based sulphonic acid resins may often be used for chemical reactions catalysed by the H+ ion, faster process times, better yields and higher product purity.

FBD300 can be used directly in aqueous systems or in organic media after conditioning with a water miscible solvent.

Dry resin is also available(less than 5% moisture).


  • Etherification reactions
  • Fuel Ethers (MTBE, ETBE, TAME); Transesterification reactions; fatty acid esters
  • Olefin hydration
  • Light alcohols (IBA, IPA, SBA)
