Summary

The esterification reaction of acrylic acid with ethanol and 1-butanol in the presence of heterogeneous solid catalysts such as: sulphonated ion-exchange resins based on styrene-divinylbenzene (Amberlyst) or perfluoroethylene (Nafion) matrix, silicotungstic acid supported on silica, tungstic oxide or zirconium sulphate supported on zirconium oxide and mesoporous cellular foam with arylsulphonic groups, has been investigated. The reactions were carried out in a solvent. The highest catalytic activities per unit weight of catalyst were observed for Amberlyst, Nafion NR50 and silicotungstic acid supported on silica, while the lowest activities were seen for Nafion SAC-13 and zirconium catalysts. The activity values (per proton) of solid acids were significantly different from those calculated by weight of catalyst and reached the highest value for Nafion SAC-13 composite.


Key words: esterification, acrylic acid, ethanol, 1-butanol, solid acids
