SuperAcid Catalysts

SuperAcid catalysts can offer many advantages: lower loadings, lower reactions temperatures, increased selectivity, fewer by-products, shorter reaction times and higher throughput.

SuperAcid catalysts can be used in a wide variety of chemical processes, including but not limited to aromatic alkylations, acylation of arenes, isomerization, oligomerization, and Fries rearrangements.

DuPont FluoroIntermediates superacid catalyst, TFESA, is less volatile than triflic acid (CF3SO3H), is comparable in reactivity, and provides easier handling in use. We have also prepared supported versions of these catalysts and introduced the ability to recycle.
