The oxidative nitration of styrenes in ethyl acetate represents a metal‐free, environmentally friendly, and sustainable technique to recover even low concentrations of NO 2 in air. Favorable features are that the product mixture comprising nitroalcohols, nitroketones, and nitro nitrates simplifies at lower concentrations of NO 2 . Experiments in a miniplant‐type 10 L wet scrubber demonstrated that the recycling technique is well applicable on larger scales at which initial NO 2 concentrations of >10 000 ppm were reliably reduced to less than 40 ppm.
