Product Overview: Amberlyst 15 (CAS 39389-20-3)
Amberlyst 15 (CAS 39389-20-3) is a strongly acidic, macroporous cation exchange resin built on a styrene-divinylbenzene matrix with sulfonic acid functional groups. It is a beaded, opaque resin with a hydrogen ionic form as shipped, and it functions as a heterogeneous solid acid catalyst for a wide range of non-aqueous organic reactions.
The resin combines a high acid site concentration (≥4.7 meq/g by dry weight) with a well-developed pore structure (surface area ≥53 m²/g, average pore diameter ~300 Å)[reference:0]. Its macroporous architecture allows efficient mass transport of reactants to the active sulfonic acid sites, which supports consistent catalytic activity across multiple reaction cycles.
Alfa Chemical supplies Amberlyst 15 from our facility in Zhengzhou, China, in both dry and wet forms with batch-specific COA and SDS. For related material science products, explore our full range.
Industrial Applications of Amberlyst 15
Four application areas where Amberlyst 15 is specified for its strong acid catalysis and ion exchange functionality.
Catalyzes the conversion of free fatty acids and triglycerides to methyl esters. Amberlyst 15 has shown high activity in biodiesel production from high-FFA feedstocks and can be recovered and reused for multiple cycles[reference:1].
Get technical data →Solid acid catalyst for Friedel-Crafts alkylation and acylation reactions. The macroporous structure enables efficient diffusion of aromatic substrates to the sulfonic acid sites.
Request a sample →Used as column packing material for HPLC analysis and as separation media for TLC and paper chromatography[reference:2]. Also applied in ion exchange separations for metal recovery.
Request technical data →Heterogeneous acid catalyst for pre-treatment of high-FFA oils and direct esterification. Offers environmental advantages over homogeneous acids and can be recovered by simple filtration[reference:3].
