反応手順

Experiments were carried out under such conditions that the mixing ratio of m-phenoxytoluene to acetic acid was varied. Using as catalysts 3 mol% of cobalt acetate tetrahydrate and 3 mol% of sodium bromide to m-phenoxytoluene and limiting the total volume of the reaction liquid to 150 ml, the experiments were carried out in the same manner as described in Example 17. The results obtained are shown in Table 21. No substantial intermediate oxidation product was obtained when the amount of acetic acide was zero. When the amount of acetic acid was 0.5 mol per mol of m-phenoxytoluene, m-phenoxybenzaldehyde was obtained at a rate of selection of 20 mol% at a conversion rate of 30%. However, this experiment showed bad reproducibility.
