MANDELIC ACID (Phenylglycollic Acid), C 8 H 8 O 3 or C 6 H 5 CH(OH) COOH, an isomer of the cresotinic and the oxymethylbenzoic acids.
Heated with sulphur it forms benzoic acid and stilbene: 2C 7 H 6 0+S = C6HS000H+C6H5CHS, 2C 6 H 5 CHS =2S +C14H12 Its addition compound with hydrocyanic acid gives mandelic acid C 6 H 5 CH(OH) COOH on hydrolysis; when heated with sodium succinate and acetic anhydride, phenyl-iso-crotonic acid C 6 H 5 CH: CH CH 2 000H is produced, which on boiling is converted into a-naphthol C 10 H 7 0H.
With urea it gives " /CH NN quinazolone I, and with mandelic nitrile and its H /C0 homologues it forms oxazole derivatives (S.
