Abstract

original image

The stereochemistry of the 1,2-cyclohexanediol intermediate plays an important role with regard to both the rate and selectivity of the production of adipic acid from cyclohexene in the absence of an organic solvent. A titanium-containing aluminophosphate molecular sieve (TAPO-5) is shown to serve as a good heterogeneous catalyst for this reaction.
