The resin catalyst has shown good catalytic performance in various esterification reactions. The ion exchange resin is a solid which is insoluble in any solvent, and its functional group is distributed on the resin, so the reaction is mainly carried out in the resin, which is heterogeneous The reaction, ion exchange resin as an excellent solid acid catalyst fully meets the requirements of green chemistry, showing a good application prospect.

Bestion catalytic resin, resin is a gel-type and macroporous styrene-based sulfonic acid resin, usually in the form of H, high temperature resistance, fast catalytic reaction, high efficiency and better product purity.
