General procedure: [0063] As shown in the following Table 3, by using carboxylic acid esters, each of which produced a water-solublealcohol, a hydrolysis reaction of a carboxylic acid ester was performed. That is, 1 mmol of the carboxylic acid ester and4 mL of water were added to the ammonium pyrosulfate catalyst (5 mol%) obtained in Example 1(1), and the mixturewas heated at 60°C to 80°C for 24 to 48 hours while stirring was performed. The reaction mixture thus obtained waspartly sampled and was analyzed by 1H NMR (CDCl3), and by comparison between the following signals, the yield of acarboxylic acid was calculated. The chemical shifts (ppm) are shown below. In addition, the results are shown in Table 3.
