30. In order to verify that the above reaction is not affected by the n-hexane:cobalt molar ratio, we carried out two experiments: The first used 0.20 g of CoAlPO-34 (ratio 0.10), so that the number of moles of cobalt corresponds to that used in the CoAlPO-18 (ratio 0.04) experiment; the second used 0.87 g of CoAlPO-18 (ratio 0.04), so thai the cobalt concentration corresponds to that used in the present study with CoAlPO-34 (ratio 0.10). Interestingly, in the case of the former, we still observed 1,6-hexanediol, 1,6-hexanedial, and adipic acid in the reaction mixture (although the conversion was only 5.2% after 24 h), whereas for the latter, we did not observe any of the above-mentioned products.
31. [1] framework sites in the AlPO-18 structure, while the conversion of n-hexane remained unaffected. If hexanoic acid or adipic acid leached cobalt from the framework, the cyclohexane molecule would have also been oxidized to cyclohexanol and cyclohexanone. See ref. [12] for further details.
