A touch of acid : Catalytic amounts of HNO 3 can trigger the aerobic oxidation of alcohols in the presence of the solid acid amberlyst‐15. The desired oxidation cycle, mediated by (H)NO x species, is in kinetic competition with the detrimental formation of N 2 O by HNO dimerization (see scheme). In situ water removal in a gas recirculation reactor increases the reaction rate and the end‐conversion by minimizing N 2 O formation and increasing the (H)NO x turnover.
