Versuchsvorschrift
The procedures of Example 1 were repeated except for employing the above-obtained catalyst (8 ml), feeding air and nitrogen at feed rates of 35 ml/min. and 70 ml/min., respectively, and feeding a methyl mandelate solution comprising methanol and methyl mandelate (6:1, by weight) at a feed rate of 17.0 g/hr., to carry out the gaseous catalytic reaction. There was obtained methyl phenylglyoxylate as α-keto acid ester. The results are set forth in Table 5.
