CD 552 macroporous strongly acidic cation exchange resin, special for catalysis

1. Introduction

Hydrolite CD 552 resin is a cation exchange resin containing a sulfonate group (-SO3H ₎ in a styrene-divinylbenzene copolymer with a macroporous structure. It is specifically used in the hexamethylene glycol production process for the removal of aldehydes. This resin exhibits excellent catalytic properties for the aldehyde-hexamethylene glycol condensation reaction, ensuring effective aldehyde removal.
