Amberlyst 35, Amberlyst 35WET, Ion Exchange Resin

Amberlyst 35WET is a macroporous, strongly acidic cation exchange catalyst designed for high efficiency in a wide range of organic reactions. Its open pore structure enhances reactant accessibility, making it an excellent choice for heterogeneous catalysis. Engineered with specialized acidic functionality, it offers superior thermal stability compared to standard polymer-based catalysts. The resin is also highly resistant to oxidation, mechanical wear, and osmotic stress.

As an advanced catalyst optimized for MTBE and TAME production, Amberlyst 35WET delivers significantly greater throughput, typically 20–40% higher than previous generation materials such as Amberlyst 15WET, while maintaining excellent olefin conversion rates and high product selectivity.

Another key advantage is its ability to increase the equilibrium constant in the reaction of isobutylene with methanol, directly contributing to higher MTBE yields. Enhanced acid site density and improved thermal resilience further support longer catalyst lifespans and more efficient overall processing.
