Procedure

When mandelic acid is oxidized in aqueous solution with pure oxygen in the presence of sunlight, no phenylglyoxylic acid is obtained as a reaction product, but only benzaldehyde, salicylaldehyde, benzoic acid and a little salicylic acid (see G. Ciamician et al., Ber. dtsch, chem. Ges. 46, page 1,559 (1913)).
