Overview

XN-17 macroporous adsorption resin catalyst is a polymer with a macroporous network and sulfonic acid groups obtained by suspension copolymerization of styrene and divinylbenzene under the action of a special pore forming agent, followed by sulfonation reaction.

Product Details

XN-17 macroporous adsorption resin catalystXN-17 Solid Acid Catalyst:

Product Introduction; Series acidic catalysts are a new type of strong acidic catalyst specifically designed to replace concentrated sulfuric acid in organic chemical synthesis reactions, including amberlyst15、amberlyst35、amberlyst36、amberlyst45、amberlyst21、amberlyst26 Waiting series. Widely used in catalysis of various chemical reactions such as esterification, etherification, alkylation, acetal, ketal, hydrolysis, hydration, ring opening polymerization, etc.

IIXN-17 macroporous adsorption resin catalystProduct composition:

The catalyst is a bead formed by suspension copolymerization of styrene and divinylbenzene under the action of a special pore forming agent, and then sulfonated to obtain a polymer with a large pore network and sulfonic acid groups.

3、 Characteristics:

Compared to using concentrated sulfuric acid as a catalyst in organic synthesis reactions Has the following characteristics:

（1） It is non corrosive and does not cause any damage to the equipment.

（2） Reusable, especially suitable for continuous equipment.

（3） The product is easy to separate, and after the reaction is complete, it only needs to be filtered to separate the product from the catalyst.

（4） No wastewater discharge, no need for neutralization and washing.

（5） Good low-temperature activity, strong selectivity, and few side reactions.
