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
