What is amberlyst 15?
General description. It is a macro reticular polystyrene based ion exchange resin with strongly acidic sulfonic group. It serves as an excellent source of strong acid. Amberlyst 15 is a heat sensitive macro-porous sulfonic ion exchange acid resin which could be used as a catalyst.
What are the structure and composition of amberlyst 15?
AMBERLYST 15WET is a strongly acidic, sulfonic acid, macroreticular polymeric resin based on crosslinked styrene divinylbenzene copolymers. Its continuous open pore structure and excellent physical, thermal and chemical stability makes it the resin of choice in many applications.
What is amberlyst resin?
AMBERLYST™ A21DRY Ion Exchange Resin is an industrial-grade, weakly basic, polymeric resin supplied in bead-form. AMBERLYST™ A21DRY can also be used for the removal of acidic materials from hydrocarbon streams where minimal water can be tolerated.
Is amberlyst acidic?
General description. Amberlyst-15 is a Brønsted acidic resin catalyst.
What is the role of the Amberlyst 15 catalyst?
Catalyst for green chemistry: Amberlyst-15 can act as a catalyst for the acylation of phenols and alcohols. They found that Amberlyst-15 is an active catalyst for the acylation of phenols and alcohols by means of acetic anhydride as an acylating agent at room temperature under heterogeneous conditions.
What is AmberLite made of?
AmberLite IRN9882 H/OH is a mixed bed composed of 40% cation resin (12% DVB) and 60% AmberLite™ IRN9766 OH Ion Exchange Resin on a volume basis. Both components are characterized by a macroporous polystyrenic structure which gives the mixed bed an exceptional physical stability.
How do you activate cation resin?
The resin can be recharged by washing it with a solution containing a high concentration of sodium ions (e.g. it has large amounts of common salt (NaCl) dissolved in it). The calcium and magnesium ions migrate from the resin, being replaced by sodium ions from the solution until a new equilibrium is reached.
What is the difference between cation anion and resin?
Anion resins and cation resins are the two most common resins used in the ion exchange process. The difference between anion and cation resins is that one is positively charged (anion) and the other is negatively charged (cation). cation resins, which attract positive ions with their negative charge.
What is AmberLite used for?
AmberLite™ Ion Exchange Resins and Polymeric Adsorbents are available in a very wide range of chemical compositions and polymer structures and have been used for decades in a high-value applications including water treatment in industrial and power generation plants, drinking water, food processing, chemical processing …
