摘要: Abstract Hybrid organic–inorganic MCM-41 silicas functionalized with perfluoroalkylsulfonic acid groups analogous to that of Nafion were prepared in a simple single step by condensation reaction between surface silanol the mesoporous and 1,2,2-trifluoro-2-hydroxy-1-trifluoromethyl-ethane sulfonic Beta-sultone. The catalysts showed very high activity for esterification long-chain fatty acids ethanol high-molecular-weight alcohols essentially complete selectivity at conversion ( > 95 % ). Acylation anisole was also possible, 4-methoxyacetophenone. more than commercial Nafion–silica composite catalysts.
