METHOD FOR CO-PRODUCTION OF CARBOXYLIC ACID AND EPSILON-CAPROLACTONE BASED ON AEROBIC OXIDATION
The present invention discloses a newly high-efficiency method for co-production of carboxylic acid and ε-caprolactone based on the aerobic oxidation, that is, under the developed catalytic system, the aldehyde is oxidized to corresponding carboxylic acid while cyclohexanone is oxidized to ε-caprolactone, realizes the co-production of carboxylic acid and ε-caprolactone. The salient features of this method include the use of cheap and readily available substrates, mild reaction conditions, environmentally friendly, and easy operation. It can realize the co-production of carboxylic acid and high value-added ε-caprolactone.
