Using the same 100-ml reactor as in Examples 1 to 14, the reaction was carried out in the presence of 1000 mg of the above-mentioned supported catalyst (2.5% Pd/Manganese oxide) under the same conditions as in the examples, that is, in each case of the addition (Comparative Example 6) or no addition (Comparative Example 7) of disodium phenoxide, 50.0 g of phenol and 1000 mg of tetra-n-butylammonium bromide were charged, and the reaction was carried out at a reaction temperature of 80° C., under a reaction pressure of 10 bar, at a flow rate of carbon monoxide of 500 ml/min, at a flow rate of oxygen of 25 ml/min and for a reaction time of 2 hours. The obtained results are shown in the following Table 2 together with other comparative examples.
