Abstract: PRODUCTION OF O-BENZOYLBENZOIC ACID BY OXIDATION OF AN INDIAN WITH OXYGEN IN THE PRESENCE OF A CATALYST IN THE LIQUID PHASE. THE PRODUCT IS A STARTING MATERIAL FOR MANY SYNTHESES (SEE FOR EXAMPLE ULLMANNS ENCYKLOPADIE DER TECHNISCHEN CHEMIE, VOLUME 3, PAGES 660 ET SEQ.). IT IS OF PARTICULAR IMPORTANCE AS A STARTING MATERIAL FOR THE MANUFACTURE OF ANTHRAQUINONE.
