Overview

This product is an immobilized catalyst that can be synthesized from sodium m-phenolsulfonate and paraformaldehyde. It contains sulfonic acid and functions as an acid catalyst. When this product is used in a batch reaction, it accomplishes efficient esterification without removing water and its reuse by recovery is also possible. In addition, various esters can be synthesized at a high yield with this catalyst by continuous-flow reaction.
