CMC 1900

Strong Acid Cation Exchange Resin

DOSHION CMC 1900 is a strongly acidic, macroporous, cation exchanger resin in spherical bead form with sulfonic acid groups. It is especially developed for heterogeneous acid catalytic application. Characteristics :
  • Outstanding physical stability & High exchange capacity : The unique structure of DOSHION CMC 1900 provides genuine porosity and a strong matrix together, with small volume change in different solutions and solvents.
  • High catalytic activity : The large surface area leads to high catalytic activity.
  • Efficient performance : The functional groups throughout the entire structure are readily accessible to liquid or gaseous reactants thus ensuring efficient performance.
  • DOSHION CMC 1900 is especially designed for the following applications :
  • Alkylation, esterification, etherification, condensation and hydrolysis
  • For specialized applications such as MTBE
