Dehydrative esterification of carboxylic acids with alcohols in water was efficiently catalyzed by hydrophobic polystyrene‐supported sulfonic acids as recoverable and reusable catalysts. In these reactions, esters were obtained in high yields without using any dehydrating agents or apparatus. The sulfonic acid contents of the catalysts and the presence of long alkyl chains on the benzene rings of polystyrene significantly affected the catalytic activity.
