SHCP-3 contained just 1.15 mmol•g -1 of SO3H sites and achieved a substrate conversion of 68 ± 8%. Catalytic conversion reached a maximum of 75 ± 2% in SHCP-5 and with increasing sulfonate content (i.e. SHCP-6 to SHCP-10), catalytic conversion decreased, reaching 60 ± 8% in SHCP-10, with a SO3H concentration of 3.8 mmol•g -1 . This emphasises the importance of other catalyst properties as well as acidity for this conversion. Figure shows each polymer in the biphasic cyclohexyl acetate/cyclohexanol and water system after catalytic conversion. Networks SHCP-5 to SHCP-8 formed quasi-stable emulsions during catalytic conversion, demonstrating amphiphilicity. As the reaction is comprised of both an organic and aqueous phase, the formation of emulsions improves the dispersion of one phase throughout the other and ensures that the catalyst resides at the organic/aqueous interface. Additionally, improved mesopore/macropore content ratios in SHCP-3 -SHCP-5 may provide good phase transfer ability, while their high surface areas ensure the substrate good access to active sites, improving conversions compared to materials with reduced mesopore/macroporosity. Selectivity in all materials was >99% for cyclohexanol, with the formation of some trace quantities of cyclohexanone in many examples.
