Strong Acidic Catalyst Resins

Cross-Linked Polystyrene Matrix Having Sulfonic Acid Group

There are SK-grade of gel type and PK-grade of porous type. The standard shipping form is sodium salt. In some cases, the hydrogen form is available for demineralization applications.

Strong Acidic Catalyst Resins Are:

The hydrogen form of our strongly acidic cation resins
Used in catalysis
An SK-grade of gel type
PK-grade of porous type
RCP of highly porous type.

The standard shipping form is hydrogen form, requiring counterion needed to run an effective solid-phase acid catalysis.

The gel-type SK catalysts can be used in aqueous reactions and where the hydrophilicity of the reaction medium is high such the esterification of methacrylic acid, ester hydrolysis, and esterification of acetic acids
with methanol.

Some special modifications of these resins are also offered for high selectivity BPA formation.

About PK Resin Grades:

They are based on a porous styrene DVB polymer matrix
Porous structure provides excellent durability against osmotic shock by swelling and shrinkage
Resins can used in similar applications as the SK type in hydrophilic mediums
Their porosity allow them to also work in non-aqueous mediums as well such as esterification of acetic acids with longer chain alcohols

Diaion® RCP160M is based on a macroporous crosslinked polystyrene matrix with sulfonic acid functional groups.

These matrices are more open and porous than conventional grade resin with increased polymer surface available for intimate contact with solutes. In catalysis, the reaction rates are faster with RCP160M than standard grade resins.

This results in a higher degree of conversion during catalytic applications. It’s the preferred resin in non-aqueous reactions, such as the hydration of olefins and alkylation of phenols.
