The Uses of ANTHRAQUINONE-2-CARBOXYLIC ACID
Anthraquinone 2-carboxylic acid (AQ) as a novel electron shuttling mediator and attached electron relay for HRP. Efficient method for the generation of hydrogen peroxide by aerobic photooxidation of 2-propanol using anthraquinone-2-carboxylic acid and molecular oxygen is investigated.
Synthesis
Anthraquinone-2-carboxylic acid is prepared from 4'-methylbenzophenone- 2-carboxylic acid by oxidation with potassium permanganate and ring closure with 5 % oleum.
