                            PhosphonicS Acid Catalysts

                            PhosphonicS heterogeneous acid catalysts are effective for a wide range of acid-catalysed processes, simplify reaction processing and reduce waste.  At process scale, the elimination of mineral acid waste streams can furnish significant savings, while at discovery scale the ability to completely remove the catalyst simply by filtration offers considerable time advantages.
