CMC 2400

Strong Acid Cation Exchange Resin

DOSHION CMC 2400 is a strongly acidic, macroporous, polymer-based resin in spherical bead form with sulfonic acid groups.It is ideally suited as a heterogeneous catalyst for organic reactions. In contrast to gel-type resins, the macroporous structure of this catalyst allows larger molecules better access to the active sites. This catalyst generally gives better results when used in media of higher polarity. DOSHION CMC 2400 is especially designed for the following applications: • Phenol alkylation with olefins • Esterification, etherification, condensation and alkylation of larger polar and non-polar molecules • Purification of phenol The special properties of this product can only be fully utilized if the technology and process used correspond to the current state-of-the-art. Further advice in this matter can be obtained from Doshion, Business Unit Ion Exchange Resins.

Additional Information & Regulations

Safety precautions Strong oxidants, e.g. nitric acid, can cause violent reactions if they come into contact with ion exchange resins.
Toxicity The safety data sheet must be observed. it contains additional data on product description, transport, storage, handling, safety and ecology.
In the European Community Ion exchange resins have to be disposed, according to the European waste nomenclature which can be accessed on the internet-site of the European Union.
It is recommended to store ion exchange resins at temperatures above the freezing point of water under roof in dry conditionswithout exposure to direct sunlight. If resin should become frozen, it should not be mechanically handled and left to thaw outgradually at ambient temperature. It must be completely thawed before handling or use. No attempt should be made toaccelarate the thawing process.
